Maxwell Render | Official public forum

Hi there,

I've just encountered something strange while applying shaders to a 3D model I bought.

The 3D model is UVW mapped and the supplied textures are already assigned to the model in Rhino. Thus far, all is well (I'm using maxwell as a plugin).



Just to check, when I make a render in Rhino with the Rhino render engine, the texturing is right.


When I make a render with Maxwell and the already rhino assigned textures, all is well too. (don't mind the moire effect due to the bad Rhino render quality... the texture really is perfect at this point)



However, when I then assign the shaders that I've made in the maxwell plugin to do a high-end render with Maxwell, suddenly the texture mapping is off and the UVW parameters seem to have been lost. I can already notice this in the Rhino OpenGL view, before launching the render itself.
The render obviously has the same symptoms:


Anyone know what I can do about this??

Tx for your input!

Are using real scale in these materials? It looks like they have been mapped with a cubic projection, which is always the case with real scale.

Hi JD,
would it be (easily) possible to lock the Real-Scale-Button when a custom UV-Layout is detected?
I'm not sure if the Plugin knows anything at all about Texture-Orientation on Geometry -but I am
at least sure that no one will ever want to utilize Real-Scale after having unwrapped and hand-textured
a piece of Geometry...

No, I don't agree with that, even if I could detect it -- if you tell the plugin to do something, it should do it.

Also if that this functionality in such contexts is nothing but nonsense?
And only leads to confusion when switched on by accident - especially
as Screen display doesn't neccesarily update when switched off again?
I beg to differ here.

Since the material editor and mapping are two different things, I don't think this would be very wise. Maybe if a real scale feature would be available for rhino itself?
But I can understand the problem since it has happened to me way to often that I accidently hit the real scale button for a material and destroying my custom mapping.

btw: how do you do unwrapped mappings rhino. is there a plugin necessary?

You have no idea how tempted I have been to remove real scale from the plugin, so that users would have no choice but to pressure McNeel to implement it directly in Rhino, where it belongs.
