Octane texturing
« on: May 26, 2016, 04:43:17 AM »
I'm having trouble trying to get the texture to lay on the grass correctly in Octane. I want the colored texture to show on the grass.  You guys showed me how to do it for vray RT and it worked great.  Bu thow do you do it for octane?

Here is the link below to the other thread you helped me on for Vray RT. need the same thing but for Octane.

I'm afraid it will not work in Octane, as any other tint effect, because Forest Color is not supported in this renderer.

You can check the compatibility list here.

Oh, it wouldn't work either in Vray RT but you showed me that workaround using just material with a mapping setting, there is no way to do that either with octane? Vray RT doesn't support tint  or forest color either, did you see the link to the forum I posted?

For octane on your Compatibility list it does say "Similar effects may be possible using the renderers own shaders."

Hi!

I've been experimenting and I think I can get something similar to the V-Ray RT trick using Octane's native maps. Try the following:



1 - Add a RGB Image map to the materials maps slots, e.g. diffuse.
2 - Add a XYZ to UVW map to the RGB Image map's Projection slot.
3 - Change the XYZ to UVW map's Coordinate Space to World space



4 - Add a 3d Transform map to the XYZ to UVW map's Transform slot.
5 - Change X Rotation to -90



6 - You can now use the remaining Rotation, Scale and Translation settings to position the map where you need it.

Here's how this looks with a UVW template applied.



I hope that helps, please let me know if you have any further questions.

Many Thanks,

Paul

Omg! thank you so much!  I couldn't wrap my head around it, I had everything right but I had no clue I needed to rotate -90. what is the reasoning behind rotating -90 I thought the texture would lay down on z axis by default?

Glad I could help out. I'm not sure quite why that is the case. I'm not an advanced Octane user but I wonder if Octane's world axis orientation is Y Up, whereas Max's is Z up. That might account for this.

Thanks!
