Just started playing around with my r20 Prime and dived right into the Node Materials. In general I am really happy with the system. There are many nodes that will give you so much control. But there are some bigger issues that cause a lot of head scratching on my side. So I thought we could use this thread for questions and discussion.
- Enforcing the reflectance workflow[/i]
If I am not missing something, you can use it only with the reflectance workflow. No old school faked-but-clean illumination models any more. :banghead:
I begged for years for a nodal system, then came the frightening reflectance overhaul, which I did not only dislike for the clunky workflow, but mainly for the noisy results. And now there is a great nodal system, but only usable with those noisy reflectance models? Am I missing something? What is wrong with Oren Nayar or Lambert if it does the job? Now I have to up the anti-aliasing for the simplest renderings? Or are there any tricks that I don’t know because I succesfully ignored the reflectance channel since its introduction?
- No help support[/i]
No context menu in the node editor has the Show Help… link which is availbale everywhere else. Manual search in the help did only lead to one page (Window menu: Node Editor). Is that really the whole help?
3. Context only for the whole material?
I really like the uv / context support in the system. Does anyone know if also the context of nodes used in the graph can be set? At the moment it seems to me as if only the context for the whole material can be set.
4. Not all known shaders
While some shaders of the old system seem to have equivalents in the new system, many others are missing. I did not check everything but notable is for example the proximal shader. Now I do not think that all are strictly necessary, but that one saved my ass so often in the past… Maybe there are other ways to achieve something like that now? Unfortunately, there is also no equivalent to Lumas
I hope someone can shed some light on these issues.
