Hello,
I am using an Octane Material with its Texture Tag's Projection set to Flat. Is there a way to limit the projection to the Front side of the object?
Thank you!

You can assign different forms of same texture to back/front side. Side node with mix texture

I tried this with a plane and it worked, but I could not get it to work with a cylinder. This method is projecting to the opposite side of the polygon face rather than the object.aoktar wrote:You can assign different forms of same texture to back/front side. Side node with mix texture
Here is my Cinema 4D scene file.
Can it be projected to the opposite side of the object with flat projection? Thank you.
* note: With native C4D texture tags, the Flat projection can be split between two materials by rotating the Flat plane's coordinates by 180 degrees.
Hi,
here is a different approach, instead of using a Side node, I have used an Octane Gradient node, but with Black and white handles very close to the middle: ciao Beppe

Thank you for the idea, Beppe.
Hi,
is there a way to use it without Mix and only one texture? I use material stacking without Compositing /Layer Mat and my flat projected decal material appears on both front and back. Using seletion set kills my material with gradient below. So is there some kind of backface culling somewhere in Octane possible?

Hi ceen,
please have a look at this solution with Triplanar mapping node, it should work also with stacked materials:

Hi Beppe Thank you!
Yes I was thinking about it, too. But while it is working ok it is a very long tweaking of values until a decal is placed correctly. And it doesn't really follow scaling of objects right? Backface Culling is really important. Please but it forward to the devs...it can't be sooo hard to implement it into a material isn't it?
