messed up alpha channel in shaders

[ianyyin]

Hi,

 

We used alpha chanel a lot in our application and we found several cases that the alpha channels are messed up in the shaders.

 

For example, the blur_2d shader, the alpha channel is dropped completely, all alpha channels are set to 0. 

there are other cases, which messed up the alpha channels as well in other shaders, like gauss, etc. There was a shader bug in one of previous post for the fragment_composite.

 

Could Unigine dev team check the shaders and check the alpha channels in next release?

 

Thanks,

Ian

Hi,

 

If you can provide us more details about this issue it would help us a lot. Such information as:

1. Unigne SDK version (alpha 2.0 or stable from 2014-07-07).
2. Video API: DX11 / OpenGL? Can it be reproduced for both API or only for one.
3. GPU Model and installed drivers version.

definitely could be useful for reproduction.

 

Also, a small test scene will be really helpful.

 

Thanks!
