Hi JD,

In C4D if I leave the source object untextured, then the render instances can receive their own texture. But in maxwell its not working. Am I missing something?

It works fine if I disable render instance ofcourse but thats prohibitive,

Strangely its working if i set up a new super simple scene, will try to find the problem in the big scene...

Ok, the problem only shows when mapping is used, and one workaround is to use c4d materials which auto convert with correct mapping, but then i cant specify priorities ...will test how much of a problem that is...

Erm, auto convert doesnt allow textures for transparency, so thats a non-starter.

Im stuck, help

Edit: I found a way to make a chevron pattern with geometry in this case, using 80 something instances, so fairly efficient;

I'm not able to reproduce this; which plugin version are you using?

[Eric Nixon 20170610100005]

4.0.5 & 3.2.5 can you PM me? I dont seem able to message you.

[JDHill]

Since the forum was redone, my account (as a developer) doesn't support private messaging.

Would I be correct to guess you're using outdated plugins because you are still using win xp? Either way, I don't think it should make a difference between the current version (4.1.3) and the ones you're using; that part of the code should not have changed. If you send (via dropbox or similar) a cinema file, I can try looking at that.

I have actually moved on to win7, its ok, I only swear at it every 10 minutes or so... (my big pc's mobo died so xp wouldnt re-authorise, lost passwords, cookies, licenses, didnt lose any work though)

I'll upgrade maxwell soon, I need to re-license/reinstall it.

I don't think this link is right, it just goes to the dropbox home page of whoever clicks it. You need to go to the file in dropbox, click the Share button, make sure it says "Anyone with the link can view this file", and click the "Copy link" link.

hope this works;

Got it, thanks. On first look, the problem is not that the material is not applied, it is rather something to do with UVs, which you should be able to confirm by changing the two materials to two simple diffuse materials. The question is how to get any UVs on the source object, if putting a material there prevents different materials being applied to instances of that object. I am looking into it.

[JDHill]

Yes, that is the problem -- Maxwell does not support having different UVs on an instance, which is how you're distributing your texture across your instances. Since this is a repeating pattern, you could still use instances, but you would need four source objects: two for the left and two for the right, with one of each having a "lower" pattern with red below white, and the other having an "upper" pattern, with white below red. You'd put the texture tags on the source geometry and set up the UVs there, and then remove the texture tags from all the instances; this would have the added benefit that you'd no longer have to manage all the mappings on individual instances.

[Eric Nixon 20170610100005]

But I want to use flat mapping, are you saying it only works with uv's?

The file I sent you has many texture tags but thats only because I was debugging the scene, they're all the same coords.

[JDHill]

No, I am saying you need to texture the source objects instead of the instances, because Maxwell doesn't support per-instance UVs.


(I think we may have some confusion, when I write UVs, I am referring the the UV coords, whether generated using flat projection, UVW mapping, or one of the other projection types)

[Eric Nixon 20170610100005]

Ah, got it, thanks, shame it doesn't work, I am using instances more and more these days with gpu memory limitations in mind.

Is it a possibility for the future? do other render engines for c4d support this?

Test render of the day attached for no reason , this morning I have been adding grunge via cubic maps and flat mapping;

Support for this (per-instance UVs) is indeed planned for the future (no ETA at this point, though).

[Eric Nixon 20170610100005]

Ok thats good news, I got confused earlier when I said that it worked with auto-converted materials.. thats not the case.
