InstanceColor is not hairs, but geometries. How do you make a setup in default renderer for that?

Here's xp forum's example setup for trail colors using standard render from Lothar.

In the link i sent there's some example scenes for this. Trails are simply splines and we use them as hairs in renderer with some materials+texture for coloring. Colors are comes from uvmapping mapped at roots. And need "w-coordinate" for extra gradient across hairs.

Yes please do this.

I did but network slaves are still missing after re-opening scenes.

Ahmet, yes.

But currently the trail shading in octane is "static". it doesnt take into account specific dynamic attributes like age or speed.

simple example: lest say i want trails that moves fast to be red...and trails that moves slow to be blue. i cant seem to find a way to currently do it with octane

The reason we ask is because u already achieved that effect with particles! it would be great to have it on trails too. and it would close a lot of the gaps still remaining with rendering particles\trails in C4D standard or Cycles4D

Anyone else on Mac using this with Nvidia drivers? I get an almost instant system freeze when I open the xp-instance-colors scene (bug report sent to Ahmet). Just wondered if anyone else was getting the same behaviour.

EDIT 1: For reference, the instance-ids.C4D scene works fine.

EDIT 2: The xp-instance-colors scene now appears to work okay. I don't have any other GPU-intensive windows open, which might help. But I have found with earlier versions, Octane might crash once or twice at first, but if I can get it up and running, it then becomes quite stable after prolonged use. Very odd!

Anyway, great update Ahmet!

I did some testing, and was able to setup the w-coordinate to shade trails with a gradient no problem, but if you use the xparticle color instance as the source of the trail gradient it only picks up the first color in the chain.

Ahmet, I understand it might not be possible, but x-particle users are hoping for a way for the trails to have a shader where vertex colors are inherited from the color properties of particles that lead each trail.

Hi Ahmet,

thank you for the new Version. Solo mode for Nodes/Textures is really cool. But if i set a Node to solo, i can´t leave this mode. How we can do this? I tried rightclick on node and select "Solo" again but i can´t get out of this.

cheers daniel

right click to empty area, select "disable solo".

Thank you Ahmet, this works.

Can we also have transform and projection nodes in bitmap node like in image node ? That would be awesome
