Team Muvizu haven't published yet (???), so I write here the link of this video (it's in italian, but i think it is understandable)
In particular, according to you I apply the texture in sketchup model and then I export the model in .ase and the texture in .jpg. Now i modify the file .ase, adding the texture. Look at the video (5:00)

Ziggy, who's just saved me hours trying to get these bloody meshes to work?
Could be!

That is superb! For some reason I cannot get the meshes as small as that! Thank you!]]> Tue, 28 Feb 2012 20:01:11 GMT http://www.muvizu.com/Forum/topic1589-collision-schmollision.aspx *GEOMOBJECT {

This creates a matchbox sized collision box on the origin point. Muvizu is happy with that, you can overlap your models with anything you like, and I don't have to edit bleedin' collision meshes! I just use transparent backdrops if I want to add surfaces that can be interacted with. That's my tuppence, anyroadup ]]> Tue, 28 Feb 2012 19:55:46 GMT http://www.muvizu.com/Forum/topic1589-collision-schmollision.aspx
As ever that has pointed me in the right direction and I have created my own collision map now.

I didn't realise that I couldn't edit it because it didn't have one ! It kind of makes sense now.

Thanks for the tips on materials as well.

I'm assuming the collision on the models that you are importing into Muvizu is the standard collision that Muvizu applies automatically, in other words there is no actual collision applied to the model you are importing. If this is the case the solution is relatively painless and will not in the end effect your materials on the models.

Import the .obj file into sketchup, and create your collision mesh to the proportions you require. Remember the basic rules of each plane having no more than four sides and all shapes to be convex. If you are presented with a concave shape, split it into small shapes with a gap between each shape.

Now delete the .obj file you imported into sketchup and export the collision mesh as per the tutorial and add it to the .ase file. Your materials will not be effected and the model should load with the new collision.

Alternatively

you can correct materials in sketchup by right clicking a face with a material applied to it and going to
1Texture
2Position

This will bring up four control handles which will let you rotate, re-size and re-position the texture on the face until it looks right.

Hope this helps
Tim]]> Tue, 28 Feb 2012 12:32:37 GMT http://www.muvizu.com/Forum/topic1589-collision-schmollision.aspx
I have some .obj models (from Arteria3d) which I need to edit the collisions on.

In order to get these models into Muvizu I use Bitrun to convert and then either use wingrep or notepad to change the things in the .ase that Muvizu doesn't like - all good.

But the collisions on some of these models are too generous and AS WE CAN'T TURN OFF COLLISIONS IN MUVIZU I need to edit the models somehow.

Now there is a tutorial of how to do this in Sketchup which I'm sure I could do, but running the obj through Sketchup screws up the textures. Instead of the texture being applied once over the model, it gets applied 1000 times but is really tiny.

I guess I either need to learn how to edit collisions in the obj before I convert, using Meshlab or something, or how to fix my texture issue in Sketchup.

As you can probably tell, I really know nothing about this, but like Ziggy I think I need to get to grips with the modelling side of things to improve my sets.

Anyone any suggestions of how to approach this, resources to use, tutorials ???

Thanks, Berty.]]> Tue, 28 Feb 2012 08:58:58 GMT
