I have this model. It is made up of many parts/objects. Almost each has a different texture or color. I wish to change say the diffusion level on all objects without changing anything else. Do I have to edit the material of each object separately or is there a quicker way? I use Bryce4. thanks!!

If they were all grouped together you might be able to edit diffusiion across the board....I'm not really sure, maybe someone else knows...:

I don't think that would do the trick... every texture/color would also be changed.

I don't think so, if you import a model that has say, 15 parts, you can texture each part separately while it's still grouped, if you select the group and change the texture yes, all the textures will be changed, but if you leave the -texture- alone and -only- change the diffusion, it should change -just- the diffusion on all objects in that group...does tha make sense? don't change anything on the group -except- diffusion....

If you select all objects in a group that share the same texture using control-left click, yes. If you select the group, or all objects in the group separately with control-left click, you are going to end up with all objects sharing the same texture. Zhann: Maybe I'm not clear on what you mean, but I don't think you can select all objects in the group and change only the diffusion without making all the objects share the same texture (the texture will be the one on the object that Bryce perceives as the first selected).

Tjohn, you could be right,I was thinking out loud and figured if I was wrong, someone would catch it....:) I did try it once, and it worked but then Bryce was doing some weird stuff and I ended up re-installing, now it does the same texture for all things, bummer....:(

The new grouper 1.4 will allow you to override the diffusion/ambience and maybe some other values with your own settings and still keep seperate textures. It only works on obj format files. It will change your original so export to a new directory before starting or it will change your poser files.

I'll try it out. However I'm not talking about poser models / objects.

When I set-up a model of many parts, I use families for parts that share the same materials. That way they can all be easily selected and the material edited. This comes in real handy when you start setting up lighting and the materials need editing to fit the lighting.

Good idea!

good idea.. but still, if you make a model or import one, you still have to select each object and assign it to a family.
