Tiling EXR textures on GPU not working

[psanitra]

I`m having trouble rendering assets that use tiling EXR textures with GPU. CPU mode renders fine. Are tiling EXR supported in GPU mode?

From console i can see :
- when Resize textures is in Full Size , vray tries to load highest resolution tiles, i my case 13 x 8k and will run out of mem...
- when Resize textures is i Mipmapping mode, it will render the image , but all objects are pure black, with white alpha.., it will not load any textures(nothing in console)

thank you.

Hello psanitra , sorry for the late reply. Looks like a bug to me, vrscene looks same as from the other DCCs but it's just not working. I've reported it and will write back here once the fix is added to the stable nightlies.

psanitra, we'll try to fix this asap. You could workaround this by setting UV -> Type: Channel instead of "Channel (Named)" at the image file node.

Cool, and thx for the tip bdancer , will give it a try.

bdancer just wanted to mention that your tip worked. On the other side there is something wrong with vray messages in console, on w10. Each time EXR tile is read, message is being written into console,thats fine. But there seems to be some delay after each line, like 5-10ms or whatever. So what happens is, that i run render,during the process it`s writing to console all the tile reads. Then render ends, but it` still writing to console. It`s writing for like 5 more minutes.., can`t stop that thing, can not close it, can not run new render. I have to kill Houdini to work again. That`s not very good , and i noticed this, and reported in beta already i think.

I'm even not sure how this "uploading texture" message is useful... We'll fix this.
