creating my own materials

[Marina Ferreira]

hi.
I looked in the forum, but sometimes there are so many tips that one can get lost...
:P

sorry, if it's a repeated item.
In my business I'm working with furniture in raw wood, and I paint/decorate it according to the clients choices.
I have several kind of finishings, imagine f.i. white base structure and brushed in green colour. This gets a very "raw" aspect, that I can't create directly in v-ray, or photoshop.

Is it possible to take a picture of a real item and use it in v-ray? any tips on the best way to do it? picture definition, size of the photographed item, ...?

thanks,
Marina

Take a picture of the subject with less highlights possible (no flashlight) than go to photoshop (or other) to remove distorsion, save your image in your preferred format (jpg?) and use it as a simple texture.
If you have some problem with tiling or seam lines, try to search on the web, there are a lot of photoshop tutorials.

thanks.
the picture I take, it should be the bigger possible, no?
I mean, the origin is a pine wood pannel, so a complex texture, with wood veigns and knots (?correct names in engligh?).
I'm having problems using the textures I find because of the scale (and also, that's not the wood finishing I'll make and want to reproduce in V-Ray); it gets too repeated because I have to shorten it to correct dimensions, in V-Ray.

So try to shot multiple pictures instead of only one and stitch them in photoshop, try to mantain always the same distance from camera and subject and try to be more perpendicular possible, also pay attention at the camera exposure to avoid grain.

And yes, generally bigger is better, but big textures eats a lot of ram so don't be exagerated.
