Question about texturing a organic form

by **manos** » Sun Apr 08, 2012 10:18 am

Hello, is there a way to map a organic form with projected material method, without octane breaking that image into small different images for each face ?
I'm trying to make a flag but when I project the image on it, octane consumes all off my valuable memory.
Thanks.

Octane hasn´t any texture projections.
You have to UV your mesh in you favorit 3d app.

I know that, what I mean is that in sketchup when I project an image on an organic shape, in this case a flag, that image is breaking into small pieces...

If you project a texture in Sketchup onto a wavy surface, if the UV distortion is beyond certain limits the material has to be saved as a distorted image, as you can't apply 4 distortions onto an image map into an OBJ file.
Therefore you cab get many images for the facets.
Can I suggest you seek advice from SCF http://forums.sketchucation.com/ where there are many debates about UV-mapping of textured images... and several free-tools to help that might indeed be better than using 'projection' [which distorts the image if it runs onto not square facets]... It's best if the material is applied 'square' onto each facets and thereby can be mapped from a single image file in the OBJ... Fredo is developing a very good new UV-mapping tool which will be published shortly - watch for that...

A new tool has just become available at Smustard.com "SketchUV" [$15] - it adds many powerful techniques for mapping textures directly inside Sketchup - with better upfront UV-mapping issues like distorted projected textures should now be a thing of the past...

Combined with the slightly more expensive 'Artisan' organic modeling toolset by the same author [Dale], and perhaps Thomthom's 'VertexTools' [cheap] and 'QuadTools' [free] - organic modeling and texturing within Sketchup is now m-u-c-h easier.

This video http://forums.sketchucation.com/viewtop ... 08#p397208 shows how to ensure 'organic' forms are mapped with one image rather than hundreds of distorted ones - although it shows 3DS export the principals apply to the SKP that can then be exported to any other file format...

Here's Fredo's [free] Material ThruPaint toolset [just launched] - that will also help you...
