bump shadows in max?!.

[super gnu]

i was moaning yesterday that despite finalrender having a system to deform shadows based on bump mapping circa 15 years ago, it has never been implemented in vray.. then i noticed that, according to the help files, Maya has a "bump shadow" setting in the vraybumpmtl, which appears to do exactly that.

i was very excited and checked the max help files. doesnt seem the option is present in the max bump mtl.?!


i read on a thread that it can be problematic with max procedurals, and sometimes gives unexpected results.. so is not included i the vraymtl. however, surely an optional tickbox would be a nice idea? if it causes problems.. untick?

im doing low res normal mapped people, and the only thing letting them down is the nasty straight shadows.across the nice normal mapped surface.

id be very happy to hear it can be enabled via maxscript or something... oh, and that it works on gpu too

Seems so:

But actually I have no idea how to use that BRDFBump plugin.. There is no Base Material input..

Yes was going to try it myself but alas only 3.6 here

I still don't have a clue how to use it. Is that BRDFBump plugin usable at all?
Some of those seem to miss crucial inputs. The layeredBRDF one doesen't seem to be usable too.

it seems there is a certain lack of documentation for this new plugin node.. maybe chaos could provide some hints? with all those nodes available, it would be good to have some tutorials, or at least a description of basic usage for each.. otherwise it seems pretty useless.

edit: maybe a new thread should be started? no point in me doing it, i dont have vray next..

Hello!
Apologies for the late response. The problem with BRDF plugins which are not usable is logged in our bug tracking system and our developers are looking into it. I'll write back soon as we have any update. For information how to use VRayPluginNodeMtl-s you can check here: https://docs.chaosgroup.com/display/...yPluginNodeMtl.

This seems fixed in the latest nightly builds (the base material slot not showing).

Best regards,

This is a stable nightly version number. We need to move the fix from the internal nightly builds to the stable ones first. I'll make a note.
