Rob Hughes (RevDr) added a comment to T54318: Render crash on GPU - glass with bump map via displacement input - High poly object.

I spent a little time playing with the 'black artifacts with bump mapping and GGX shader yesterday.

Rob Hughes (RevDr) added a comment to T54546: Texture paint after render whilst in texture paint mode causes crash - something in undo code seems to be the cause.

OK - have spent a little time looking at the code.

Rob Hughes (RevDr) added a comment to T54554: bpy.ops.paint.image_paint with a texture requires initialization with manual paint stroke otherwise color not quite right.

Having looked at the code it appears that the color space initialization for the texture is done in
paint_stroke.c
function: paint_brush_update (particualy lines 239->261)

I have done a little further investigation.

Rob Hughes (RevDr) added a comment to T54494: Undo with text editor and run script crashes blender.

Although I am sure the change will fix the crash. What I am unsure of (as I don't really know the code) is if calling the function txt_do_undo with text->undo_pos with a value of -1 is a code design feature of if it indicates something else is not right somewhere else.

Thanks for the changes/ However, the basic test scene is still crashing for me in Debug,

You probably know this already - but just in case - I tested it with the Principled shader and the same problem occurs with multiscatter GGX with that shader too.

Rob Hughes (RevDr) added a comment to T54318: Render crash on GPU - glass with bump map via displacement input - High poly object.

Whilst I am sure you know what I mean by "black artifacts with bump mapping glass shader" objects issue, I have attached the two images which highlights the significantly better image generated with multiscatter which clearly does not suffer from the artifacts.

It doesn't crash with GGX.

Rob Hughes (RevDr) added a comment to T49059: CUDA error: Launch failed in cuCtxSynchronize().

Hi,
I was having this problem this week.
I knew my scene was not using all my graphics memory (GTX970) but blender kept failing wih cuCtxSynchronize (I think it was that and not initialize) or sometimes blender was crashing altogether.
