[HOU-1362] Issues after VRay version update

[jurweer]

Hi guys,

we are trying to optimize our scenes and have issues fixed by updateing from the 15th of october release to the 12th of november release.
it seems that some features are not propgated from older scenes even though the core is 4.12.03 on both versions:

on an older scene that is being opened with latest release, the AO pass looks horrible. the entire object shows artifacts. adjusting the secondary ray bias doesnt help. reverting to the old vray version works fine.
the ao look fine on a fresh scene with the latest release.

the material override doesnt work on older scenes being opened with the latest release. it works on a fresh scene with the latest release. reverting works fine.
extratex with a dirt map is not outputting any AOV's btw.
also - we dont need it for this project - how would one deal with displacement with a material override activated? we intend the override to create a techpass ROP with a shadow pass, AO, specific masks etc

we need to update to get rid of some of the bugs (mostly subnets) which i read get more and more fixed (yeey!). however, we can afford to rebuild our scenes after every update, if specific features dont work anymore.
still looking around if there are any inconsistencies and will write it here if i found some.

Scene file?

Material override feature was completely redesigned after release.
Still scene file may help.

Scene file? In material AOVs or in "Render Elements"?

So, it doesn't work now or? Scene?

Sorry, i didnt write it down properly. There is no output in the ExtraTex Render Element, when the material override is activated. This happens in the old release. In the new release coming from the old release there is no output whatsoever. this ofcourse could be because of the redesigned functionality you mentioned that is being misinterpreted from the old scene (or something of the kind).
In a fresh new scene, there is also no extraTex output in the Render element. (i'll add a fresh scene, turn off material override and it works)

> how would one deal with displacement with a material override activated?

This is more a general question. If i want to make a shadowpass ROP with 1 light, a shadow catcher and a shadow caster, i need the displacement. But i want to minimize shading rendering. In maya i recall we overwrote the shader on the shading group but kept the displacement connection on that same shading group.
How do we go about in houdini?


Sending you an email with a scene because of NDA's!

Thanks

I'll check if this could be fixed.

A can't see why u can't do this now, so just write me if that doesn't work for you (with a scene)
