I need to make HDRI invisible to the camera? Or another possible solution is making a plane emitter visible only to the camera. Basically I need pure white background (which doesn't affect other objects at all) while objects is lit by HDRI.

It would be nice to do this within Blender

Is there a way to increase this value? It seems that CUDA is less limited in this sense.

I also have a problem with OpenCL rendering (viewport preview rendering). It freezes. I suppose this is due to CL_DEVICE_MAX_MEM_ALLOC_SIZE=536870912. But why is it only ~500 MB while my card has 2GB dedicated GPU memory?

Thanks for your help and good explanation

I added a little bit of emission. This is a hack, but there seems to be a lack of transmitted luminosity without that. Could there be a physically based way to do this?

Yep. I attached that .blend with the texture in the previous post.

I've tried to do this with the same texture as in the photo and it doesn't seem to work properly. I've get some weird inverted shading. Symbols appear lighter than the rest of the sheet. What might cause this?

Hello. How to create such a translucent material (a sheet of paper) with some image texture? In the photo I'm directing the sheet towards a lamp and able to read what is printed on another side. Is it possible to do this with LuxCoreRender in Blender?
