Adding texture material to imported dwg model

#1

I can drag and drop any texture onto C4D geometry just fine,
but when I drop a texture onto geometry imported as dwg,
the texture explodes all over the face of it. Does anyone know
how to fix textures added to imported dwg geometry? The
dwg model comes from Revit and does everything very well,
except get texture materials to drop onto it properly.

your import does not to have proper UVW maps which is a common problem on imports, but I guess flat ord cubic mapping would be fine for you.

So please open the help of C4D and learn about the different types of projection of textures and the coresponding Tag, (The Texture Sphere next to ypur object in the object manager)

this is a very basic question -> the c4d help should give you all the information you need.

Thanks very much for your reply. You said: ā€œdoes not have proper UVW mapsā€
And you said to look in help. I do look in help when I know what words to use for
looking in help, otherwise I go to a forum like this, hoping someone will know
how to interpret the problem I am describing so I can find it in help. The only
thing I was able to do about this was randomly check and uncheck controls
and hope something happens. And it DID happen. I got the image to show
properly on the model. Now I just need to find out how scale that image.
AND try to recreate my random actions that lead to showing the material
image, so I can get back to that and make it happen again.
I finally realized how much I love the way C4D renders. They way
you can play with the lighting. Not just like from the sun like V-ray.

If youā€™re a Lynda.com member (or have access through your local library) these two videos should get you started:

These are relevant help pages:

Hereā€™s an older Cineversity tutorial:

Some tips for you. The texture tag is quite powerful. If you click it once, it brings up a panel with a drop-down menu, where you can apply different types of projection mapping: Planar, UVW, Cylindrical etc. Youā€™re probably best with Cubic. Play around with these to see what they look like.

The controls beneath let you move the image around, stretch it and tile it (ie, have it repeat over and over).

If you right-click on the texture tag itself, it brings up another menu, where you can use ā€˜Fit to Object;ā€™ which fits the texture to the model (or polygon section) itā€™s applied to.

To move the texture manually, enter Texture Mode (click the checkerboard icon on the far left, second one down). Now you can move, scale and rotate the texture and place it as you see fit. Donā€™t forget to go back into Object Mode once youā€™re finished.

You should play with all these options, see how it affects your textures, and understand projection and placement before moving to UV mapping ā€“ but its definitely something you need to understand moving forward. (In short the surface of a model can have U, V and W coordinates, just like an object has X, Y and Z coordinates. This enables C4D to map the textures accurately across all the polygons. As images are mostly 2D we only use the U and V coordinates.)

Thereā€™s a lot of useful stuff in the Help menu under UVW Tag.

Thanks guys so much. All I really wanted to
accomplish with this post was to determine
that it COULD BE DONE. And I stumbled
onto some settings that gave me the texture
image on the geometry, even if not scaled.
So then I knew C4D was going to be my
baby. Iā€™ll only be using it for rendering
my Revit models, and of course there
will be plenty to learn just for that. I leaned
enough about 3Ds Max to use it for
rendering, and I learned enough about
SketchUp to use that for rendering,
both have the V-ray add-on. As for
what most of you people do with
C4D, create digital models, I donā€™t
know why anyone would use that
ā€œMicky Mouseā€ SketchUp instead of
the much more ā€œgrown-upā€ C4d.
And 3Ds Max is an old bloated
3D program that is tangled up
with the ā€œwarmongeringā€ Autodesk.
I love C4D. Oh yeah, thereā€™s Blender,
okay fine, if someone wants to
start with that. And I donā€™t want
to get in trouble for not mentioning
Rhino, that is probably okay too.
Hope to see all of you again soon,
thanks much.

I donā€™t think so. How would I go about
finding someone to render my models
using C4D? I have a steady stream of
models that I need rendered. I know
it wouldnā€™t be all that hard learning
the material editor, but I would rather
pay someone to do that. Any ideas
from anyone?

#8

Sure, Iā€™d be happy to. Iā€™ve PMed you.

#9

Absolutely. Thank you. Iā€™ll get back to you in a couple
of hours, I have to go somewhere.

Darth_Mole, this is the first time I have
been to this forum and I donā€™t know
how someone would communicate
with another member. I did get a
message from you in my email, but
the only way I seen to reply was by
a link back to this forum. Do you
know how that works?

#11

Not much help from YouTube, but
spending hours and hours using
trial and error, I got the texture
image onto the model. I could
figure out everything about C4D
that way, but I donā€™t really have
the time because I build Revit
models for architects. Iā€™ve always
used V-ray but C4D reveals the
geometry better, for the building
department.
