Group particles into four parts
olivetty replied to cgartashish's topic in General Houdini Questions
This is magic! Thanks celd for this, looks so useful! -
How did you compute it using the polyframe and then passed it on to RS? I think this would be awesomely useful information as I've encountered this before. Usually when RS slows down hard is because it's going out of core (not enough VRAM left).

Redshift Volume Motion Blur need Help!
olivetty replied to Litesound's topic in Lighting & Rendering
MB on volumes in RS just doesn't work at the moment. It tries to "smear"/"displace" the volume using the velocity data but it's not great to say the least. Maybe there's something you can do to the data and render out some kind of motion vector pass or something? I don't know -
What is your workflow to maintain color fidelity?
olivetty replied to anbt's topic in Lighting & Rendering
There's a post FX tab on the render rop that has tick boxes for baking in certain settings from the RV (Like LUTs, Bloom, or CM). The RV shows you what your linear picture will look like when baked to sRGB (the screenshot you posted). It's just a view-transform. Your picture is still linear just viewing it in sRGB. The color picker can be changed, either sRGB or Linear will be correct, I don't know which though! -
I'm doing something similair at the moment and was wondering what you ended up doing on your part? How did you solve the slicing and rendering bit?

redshift Rendering Ramp Color created in VOP in RedShift
olivetty replied to MantaRay's topic in Lighting & Rendering
Don't use particle lookup. Use Color User Data instead and when you've written your attrib name reload the RV! -
Awesome thread! Loooove it!!! Beautifully executed!!

Sorry for reviving an old thread, but that last part, about driving discp with my temp attrib, how the hell do I merge the two attribs together so that it affects both disp and emitcolor? Right now I have a surface cache node in the particle_fluid geometry node which feeds into to different nodes (color1 which is just a rampcolor from an attrib = temp) and I pass that out to attrib rename and rename it from Cd to emitcolor and put that into an attribcopy together with the surface cache (this is the lava shelf tool of setting things up in H15). How do I create infinite attributes affected by temp which all feed into my null at the end (drive basecolor with temp, displace amount with temp etc)?

Did you ever resolve this?
