Hi,

I was making a particle simulation. I was adding color using the 'pack color in the uv map', in the particles properties tab.
When the render finish in the IPR, the colors change. When Is rendering the colors are ok.
I am attaching two images to show the problem, and the scene file.

Thanks,

Saulo

What a weird issue! Sorry, but I can't reproduce it here using your scene and this latest 2019.1 RC2 build. Do you know if the problem could be related to the denoising? What happens if you disable it?

Thanks,

Hi Juanjo,


You are right. The problem is when the denoised version is activated.

and I am also have warning messages when I open this scene.

Load warnings for C:/Users/Saulo/Desktop/particles_bug/particles_bug.hiplc

Warning: Problem while synchronizing child node:
Warning: Skipping unrecognized parameter "edgesRounding".
[/obj/octane_light1/light_shader/light_shader/NT_MAT_DIFFUSE1]

Warning: Problem while synchronizing child node:
Warning: Unknown channel(s) "edgesRounding" converted to spare parameter(s).
[/obj/octane_light1/light_shader/spotlight_geo/octane_vopnet/NT_MAT_DIFFUSE1]

The warnings are related to the deprecated edgesRounding parameters, now replaced by a proper node. You can ignore them.

About the problem with the denoiser, it is weird that I can't see it here. What NVIDIA drivers are you using?

Thanks,

I am using Nvidia Studio driver version 430.86.

It is strange also because I have other scenes with particles, and this problem doesn´t appear. I tested this from Rohan Dalvi, and It is rendering correct.

I used the 2018.1 version, and this problem does not appear.

It seems some kind of bug in the denoiser, but here I can't reproduce it. Do you know if the Standalone 2019.1 RC2 has the same problem on your system? You could export the scene to an .orbx file from the IPR window and check if the same happens in Standalone, to report this file to the Octane core devs.

Thanks,

I can´t, because I have an Indie License.

Hi,
I seem to be having trouble playing around with the texture border mode. If i'm not mistaken in previous octane versions, all the modes worked?
Wrap and Mirror modes work, the rest do not. Could you confirm?

thanks
