Meanwhile in live chat support the guy is telling me that the acrobat code is genuine but the CS5 half is pirated and the only resolution is "buy our sub, discounted!" Meanwhile we receive an email from Adobe support saying if it is a real pirate then the entire suite (BOTH serials) shouldn't work - which isn't the chase. And now she tells me I have to go back 10 years to find a 'proof of purchase' to 'escalate' (not fix) this. And then she tried to tell me the reason why my serial doesn't work is because I'm in North America now so the region is bad - but my Acrobat installation as of last week worked fine and just the CS5 half is 'invalid' - so she let that argument drop too. Then she tells me the reseller isn't genuine, "it's not on adobe's site! Go to to check!" until I yelled over her to go look under Hong Kong region - then she let that argument drop. I installed License crawler (still waiting for Belarc to reply) and it found the necessary code. With the upgrade to a new desktop, MAGICALLY, the CS5 serial is revoked because it is 'pirated'. Thanks to Sunny.sunny and Randy Hagan for help. But we pull illustrator and INDD files from our archives once in a while. We are on a photoshop subscription now because it is the one program we use frequently. We got TWO serial codes - one for CS5 and one for Acrobat. With one redemption code we got from Adobe's OWN WEBSITE. We purchased a copy of CS5 Design SUITE via a lisenced reseller whose name is STILL on their website. I will like to add my name to the 'screwed by Adobe' list. But I still want my CS6 running on my old iMac. I recently purchased CC, running on my new iMac. I managed to find Adobe's "Thank you for the purchase" email, sent directly after making the CS6 purchase, and then another with my serial number for CS6.Įven today, on my account, there is a record of my registered CS4, the CS5 purchase and the CS6 order number and serial number.īut I don't have the invoice, which is what they are asking for. I have been trying to prove that I purchased these products from Adobe, and that THEY gave me the serial numbers. Just this weekend, I had to reinstall it.Īlas - your serial number has been revoked. I purchased CS4 from B&H in 2009, registered it with the serial number. Oh, so so sorry that this happened to you.

Simple Pregnancy Mode lacks any additional pregnancy mechanics and the chances of getting pregnant are manually decided by the player. Setting ‘Pregnancy Mode’ decides about additional pregnancy-related mechanics and the way pregnancy is initiated from sex.At the same time, animations that are used for two males will allow that Sim to always be placed as the “bottom”. Setting ‘Sim Specific Gender Recognition’ enables new interactions on actively selected Sim that allows you to decide about their gender recognition.įor example, selecting the female option on a male Sim will allow him to be able to occupy animation roles that were meant for females.Setting ‘Recognize Male/Females As Both’ allows to override all animations roles of a specific gender to be allowed for everybody.įor example, allowing to recognize females as both means that all female animation roles can additionally be occupied by males which can potentially create a lot more gay-oriented sex position.This can cause issues with Sims performing incorrect roles (like female penetrating a male and not the other way). Gender Identity means that males can have a vagina and females can have a penis if that is specified in CAS Gender Settings.Īnything Goes means that Sims gender is ignored and they will fit all and every animation no matter what. Sex Identity means that male Sims always have a penis and female Sims always have a vagina. Sims in sex are placed in roles that fit their gender to properly represent the current animation (like a male penetrating female and not the other way). Setting ‘Gender Recognition Type’ decides about “actors gender roles” in sex.Animations will progress with Stage Only rules and instead of stopping at the end, pick a next random animation. Random Progression means that animations will switch to any random animation within the current sex category and/or switch the sex category.įull Progression is the hybrid between Stage Only and Random. ![]() ![]() Once the order reaches the last animation, progression is stopped. Stage Only Progression means that animations will be restricted to the order that the creator of animations specified. Setting ‘Sex Progression Settings’ decides about the way Sims will choose the next sex position.Setting 'Vanilla Interactions Switch' disables all base game interactions from the pie menu when Sim is in sex to improve navigation.Im most interested in quality and realism so if you share my thoughts and you like this style of gameplay - youre in the right place. This section only explains the most complex settings. GreyNaya Animations for WickedWhims Hi community Im creating animations for the great Wickedwhims mod by TURBODRIVER. ![]() Free church backgrounds for propresenter4/15/2024 ![]() ![]() Fresh shapes, fills, alignment guides, text controls, and more have been added that make outside presentation software like PowerPoint unnecessary. ProPresenter’s new Editor has been rewritten with new features that users have requested most for slide design. For example, you could have a fullscreen clock on one display and song lyrics on another. Plus, you can now send separate stage display looks to different screens in your space. With Pro7, there is a brand new Stage Display editor that allows you to create layouts with similar controls as creating slides. In past versions, formatting and display options for stage displays, or “confidence monitors,” was pretty limited. Another great feature of these new screen controls is that the software will remember your output settings, even after restarting or unplugging. You can output to as many screens as your computer will allow with more customization than ever. Since most computers now support multiple outputs natively, Pro7 allows you to fully control what content goes to each of your screens, through SDI, NDI, and HDMI. In the past, many ProPresenter users utilized the Multiscreen Module and TripleHead2Go adapters to achieve multiple screen outputs. Built-In Configuration For Multiple Screens With Pro7, Renewed Vision has built a new platform from the ground up to ensure an identical 64-bit experience on both Windows and Mac. Even though the past few versions have included a Windows option, it has always received new updates much later and been more of a little brother to the Mac version. ![]() ![]() Since its original release, ProPresenter has been a Mac-focused program. This is great for increased visibility when running your slides. Without affecting your slide formatting that displays to your audience, you can now change the font, color, size, and more of your slides on your operator display. Increased Text Size For OperatorsĪ new EasyView feature allows complete customization of slide text specifically on the operator side. Is your congregation multilingual? Or, do you ever need to compare two different translations of a Bible verse in your teaching? This new feature allows you to quickly create slides that show multiple translations of the Bible on your screens. Display Multiple Scripture Translations At One Time Plus, in the new “preview” area on the right, you can view the output of any of your screens.Ģ. Other great changes include more convenient buttons to clear elements, a helpful search bar, and multiple presentation libraries. You’ll love the new dark mode that makes the software much easier on your eyes when working in darker production environments. The first big change that we noticed with ProPresenter 7 is a massive overhaul to their interface. If you’re considering updating from a previous version, or perhaps jumping into this software for the first time, here’s a quick look at some of the best new features in Pro7. Our team at Church Motion Graphics are long-time users of this presentation tool, so we were excited to get our hands on ProPresenter 7. The best part? It’s available to download immediately. This new release has been highly anticipated by church tech teams over the past few months as the company has dropped hints of their newest update. Today, Renewed Vision held a keynote and live stream announcing a brand new version of their popular church presentation software, ProPresenter. ![]() Quest diagnostic appointment4/15/2024 ![]() ![]() Your results will always be located in your account area.

The effectiveness of an obstacle in diffracting sound is determined by the acoustical size of the obstacle. Obstacles capable of diffracting (bending) sound must be large compared to the wavelength of the sound involved. The process by which this change of direction takes place is called diffraction. Obstacles can cause sound to be changed in its direction from its original path. This is considered a desirable effect due to the fact that the air conditioning noise is reduced.ġ0 Diffraction of Sound Wavefronts and rays of sound travel in straight lines, except when something gets in the way. Example: when a sound wave (noise) traveling in an air conditioning duct suddenly encounters the large open space of the room, the impedance mismatch reflects a significant portion of the sound back toward the source. Mismatches in impedance give rise to reflections, which cause numerous undesirable effects, but can sometimes be desirable effects instead. A standing wave is a resonance condition in an enclosed space in which sound waves traveling in one direction interact with those traveling in the opposite direction, resulting in a stable condition.ĩ Reflection of Sound from Impedance Irregularities This concept is used in microphone design to create highly directional microphones known as parabolic mics.Ĩ Standing Waves The concept of standing waves is directly dependent on the reflection of sound. The precision with which sound is focused is determined by the shape of the concave surface.Ī parabola has the characteristic of focusing sound precisely to a point. Plane wavefronts of sound striking a concave surface tend to be focused to a point. This amounts to a diffusion of the impinging sound. Reflection of plane wavefronts of sound from a solid convex surface tends to scatter the sound energy in many directions. The pressure at the face of a perfectly reflecting surface is twice that of a perfectly absorbing surface. The mid/high audible frequencies have been called the specular frequencies because sound in this range acts like light rays on a mirror.Ĥ Angle of Reflection Sound follows the same rule as light: the angle of incidence is equal to the angle of reflection. Sound above 300 – 400 Hz is best considered as traveling in rays. Below 300 – 400 Hz, sound is best considered as waves. The image source is located the same distance behind the wall as the real source is in front of the wall. ![]() Like a mirror, the reflected wavefronts act as though they originated from a sound image. The diagram shows the reflection of waves from a sound source from a rigid, plane wall surface. As the sound waves encounter obstacles or surfaces, such as walls, their direction of travel is changed, i.e., they are reflected. 1 Reflection, Diffraction, Refraction, DiffusionĪcoustics Reflection, Diffraction, Refraction, DiffusionĢ Reflection of Sound If a sound is activated in a room, sound travels radially in all directions. ![]() AuthorWrite something about yourself.
