Does triplanar work for you in max distance rollout?

Triplanar is just a mapping shader, it needs input texmap to work and yes, it should work in max distance slot without problems.

Yes, it should, but here it doesn't!

Of course I use a bitmap in triplanar!! With this setup applied, I can change triplanar size, blend modes for max distance texture and value for max distance, but it doesnt change anything.
So that's why I asked. Just for curiousity! It seems as if there is a bug!

Cheers...

Ok, ok, no need to shout :] I can't know everyone's level of expertise, sorry for asuming that you don't know the basics.

Triplanar in AO is working in 3ds Max (see attached example*), so it definitely should work in C4D too. If you sure that it's not working, then report it as a bug.

* - on the left is regular mapping (notice texture streching), on the right is triplanar.

After some testing, sometimes Triplanar doesn't seem to be working (and sometimes it is) - note that this is Triplanar overall, not just when used in the AO map. We are investigating, under internal tracking 316011885.

Hey buddy! Did you achieve the result you were looking for with the AO map.
I'm trying to do the same thing with no success.

sorry this is an old post and probably not relevant anymore, but I actually managed to do this effect with the Corona AO shader and I've used a dirt map for the distance
i watched a corona tutorial about this on youtube :

list=PLt4UrWcQaAX9V8_rM8HHNGu2xRLfLBOP3

also attached my result. Thanks.

Love that result from Max, has anyone rolled this out into C4D?

Thanks!

Thanks! Yeah that does help, nice shot!
Is that AO simply in your diffuse colour layer?
Thanks!

Sorry about that, I didn't realize I had cut that part off. As there is no diffuse in metal, the AO is residing in the reflection colour channel. I hope that helps :)
