Blank images when I tried to render with different tile sizes - render_32x16 and render_32x32

[kvsaiakhil-TAMU]

Hello,

I am seeing black or unclear images when I tried to render with tile sizes - render_32x16 and render_32x32. Can you please help me fix these issues?

Expected:

Output:

Also, is it possible to change the renderCUDA block size from (8,4,1) to any other size such as (4,2,1) etc to understand the impact of block size change? I tried this as well and I am getting blank/black rendered images as output.

Please share your suggestions.

Thank you
