Houdini File gets corrupt after replace of Text June 15, 2018, 1:03 p.m.

Did you save the hip file as Text? The default is binary, which won't react well to replacements.

Why are rendered TIFF output from Houdini only readable in Image Viewer and not other TIFF readers? June 13, 2018, 3:50 p.m.

Emission renders color without any alpha (A=0), as it is purely additive. So when when you blend it with a standard over, you get C = Ce + (1-0) * Cbg, where 0 is the emissive alpha. If there was an Alpha, it isn't emissive anymore - it'll block some of the color from behind it. So I suspect the other viewer was premultiplying color by alpha, and we all know how multiplying by zero works out

Yes, Vulkan and Metal have compute capabilities built in. OpenGL 4.4 also has Compute Shaders built in. There are some minor differences between CL and GL's compute (precision of math functions, for one, CL is more accurate, GL is “good enough for graphics”).

And indeed - too soon to panic.
