Every time I input a video to CTA I get the following error: " YOUR SYSTEM CAN NOT SYSPORT NON-POWER OF 2 VIDEO TEXTURES" everything worked ok when I first installed CTA. - What happened? How can I fix it?

Hi..

What are the dimensions of the video you are trying to use? This error would normally only be shown when you try to use a video which is not power of 2 which your hardware doesn't support.

If it is happening on all videos of standard dimensions then please contact Reallusion Support using the link below. They will be able to check your system and help diagnose the problem.

Thanks.

Is there a link I can go to that will explain what "the power of 2". I never herd of this before. What is the power of 2 video?

Certain graphics hardware may require that textures be in a power of 2 in both dimensions.

So this means 1, 2, 4 , 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096 etc are acceptable. The textures also don't normally have to be square but should be power of 2. So 1024 x 512 will be fine also.

So what can happen is that if you use a video of a standard size like 640 x 480 it will be converted to a video texture of say 512 x 512 to maintain the power of 2 structure. When your hardware doesn't handle this you get an error like the one you received.

With this in mind, if you try to keep your videos power of 2 you shouldn't encounter the error message you have been receiving.

Hope this helps.
