just doing some tests with RC5 in Max...

seems to be impossible to use uvw-mappings with any any kind of bitmap?

"UVW channels (0) on object "stein01" not enough for material "steinplatte"

i used a mxm-file created in studio...is this some bug or am I doing something wrong?
do mxm - files work with bitmaps in the plugin?

thank you very much for any answer

it's a known bug, when importing back in max a mxm done in studio uv coordinates get messed up. you're better off rendering from studio if the scene you're working on is not too complex.

This ought to go in the "PLUGIN BUGS" Sticky. It's a bit of a showstopper if you want to use MXM's in an animation...

Note that textures in Maxwell Diffuse works. Plastic works sort of, but not bumpmaps.

Yes, I usually apply a diffuse to setup the uvw map in 3dsmax and then in studio I change the applyed material in the way I want.

thank you very much...that's what i feared

so i will try studio again...

Me too, then replace the two bsdf layers with either an mxm or my own material in Studio.

Do I understand U correct... :

1: If U have a big complex scene, then it is difficult to controlled the UV map on severals objects?

2: If we imagine that we have a box, and applying a bitmap (example: stones) on it, then it is impossible to controlled the UV map on the different side of the box?

To me this is only true for Studio. I don't use Studio for any UV mapping.
If the UV maps are correct in my application before exporting them to Studio, then there are no issues with Studio and it's handling of UV maps, regardless of scene size and complexity.

It's using Studio's own UV mapping system that I find I get the most errors with and less control of my UVs.

Hi Kenneth,

If you correctly map everything in Max, (ie two UVWmaps, both set to box, one rotated 45 degrees) and apply a material that has maps in both of those channels (ie one diffuse, one bump) then the mapping will work in studio without a problem.

Am I doing something wrong? I was running into the same problem with the error message, so I went into studio and applied projectors and now it works.

But I thought it was supposed to be that if you applied a UVW map in Max then you could apply the material in Studio and it would render. That's not working for me. Even though I've applied UVW maps to all my objects, I still have to apply projectors in Studio because none of them have them and render as "default."

If anyone and follow the rambing logic behind that post I would appreciate some help. Thanks.

[Tim Ellis]

j_man, thanks that's a handy tip.




misterasset, this is my workflow with UV maps, from modeling application through to Studio.

I model my object in Blender 3D and do any UV mapping to the mesh before I export it.

I then export this model as an .OBJ file to retain the smoothing and UV mapping I've applied.

I import this .OBJ file into 3DSMax. I then apply a UVW Unwrap modifier, in the stack for the model. If I click the UVW Unwrap 'Edit' button, I can check the mapping is as it was in Blender.

I now add a Maxwell Plastic material to the material editor. I then load up the colour map I will be using in Studio and the bump map.

I assign this material to the model and render with a Maxwell camera, to create the .MXS file.

I then open Studio and import the .MXS file to my scene, if it's an addition to the scene, I just open it if it's a complete scene.

I then delete the material for the model and create a new one, using the maps I used in 3DSMax. Then apply that to the model.

The projector list for the model will have 'Locked' selected. There's no need to change this otherwise you will lose the UV map data, if you select box or similar.


I hope this helps,

Tim.

Kenneth, I tried exactly your first item above:
- Make a Box, Turn to Poly, Select 1 side of box and set material ID=2, rest = 1.
- Create Multi/Sub Material with 2 slots, Slot 1 = Maxwell diffuse, Color Map = Bitmap, map channel 1; Slot 2 = Maxwell diffuse, Color Map = Bitmap (another one), map channel 2.
- Apply two UVW Mapping modifiers, different mapping, one is channel 1 the other channel 2.

Works well.

(The "locked" projector means that UVW coordinates are coming from MAX, so that is just good.)

Please explain what it is that "Doesn't work" exactly?

I did some more experiments and I only got the error message 'Error: UVW channels (0) on object "Name11" not enough for material "material #667' if I don't add a texture map to the material before export.

So, do everything as you have been, but before export from 3DSMax make sure you have loaded a texture (jpg, tga, png etc) into the colour slot for the maxwell material.

If the object is correctly UV mapped, has a maxwell material assigned and then exported without an image texture, then Studio or the plugin will give the error message.

Make sure you have an image loaded before you try to export.

Hope this helps,

Tim.

BTW Kenneth,

the plugin materials in Max still have the problem where when you add a bitmap to a material, the little checkbox under the "maps" group for that map doesn't get checked, so you need to do this by hand to make sure the bitmap is properly assigned and the mapping is exported.

[j_man]

you don't need any extra plugins, but you do need the correct plugin! did you install the new max plugin from the next limit/maxwell/plugins folder after installing RC5?
Maybe you should upload a sample max file to have a look at. Can't really think of anything else.

Josh.

[j_man]

we've suggested everything else, so sometimes it's the simplest thing. now how about posting that file, even if you just maked a quick test scene that you know doesn't work. remember to include all of the maps.

J,
