Photoshop can't add textures, but it can edit them.

As for preserving with 3DS, I've only worked with OBJ, and they get saved as 3 files, the OBJ file, a JPG texture, and an MTL file that matches them together.

Both props are looking very good. If the final files are too large to attach here, just email them to me. (dnelson at this domain)

E-mail sent just to check a few things before proceding further. Ducks in a row and stuff.

I did not open this for a while thinking it as indeed the photographic type of model you wanted..LOL

Sign up for Turbo Squid, although they sell 3D models they have a ton of free ones, just search the item and change the order to show by cost and the free ones are at the top. I have grabbed a few objects to use in CS3 this way.

As a note if anybody applies texture using plugins or built in texture libraries they will not make it to PS, they have to be bitmaps. I have found issues with mapping, I did a hockey puck and found that the mapping was not honored in Photoshop, this was because I used a cylinder mapping and Photoshop just slapped it on square.

I finally got the 3D file exported with the texture files. I can see the texture loaded in the layers when I load it into Photoshop, but I can't see it on the image in Photoshop. If you have an idea how to get it to show, please let me know. Any way, here are some images. I would email the files to you, but I don't see anyway to add an attachment to your email.

Got the bowl file, though it looks a lot different in Photoshop. Also got the pepper file.

First thing I noticed was that Photoshop won't let you rotate more than one object. Second was that 3D objects in Photoshop are on layers above and below each other, just like photo layers, so they can't interact. I can't even export them simultaneously to the Strata render filter.

Here's a quick b/w mockup of what the final challenge will look like, using the two models so far. It's supposed to be b/w, which works out because I can't get Stroker's pepper to show in color. (see link in post #4 for context)

Hope you don't mind if I link to your files. That way everyone can play along. If you make improvements just let us know:

Pepper
Bowl

If you have any changes to make to the models let me know and I'll replace the zips. Once you're satisfied, let me know and I'll start a new thread with the challenge.

I will most certaintly keep working on the pepper model. Even if someone comes along with a much better model, I'll keep working on it for personal reasons. There is something about it that has piqued my interest, and that doesn't happen very often.

Linking to my files is not a problem. As far as PS goes, you are correct, PS puts the object in layers, that look like a smart object. You can reposition the object to get it to look like you want, and then rasterize, or convert it to a smart object. I never could get it to display the material though, and I am not sure if it was something that I was doing incorrectly. It will be interesting to see what others come up with. Let me know if you need anything else.

I had no problem seeing the texture with the OBJ bowl, I re-saved the data from Studio as a 3DS file and found the texture looked better defined in Photoshop when opened from the 3DS.

I re-saved the texture as a jpg just to save space as I am at work and cannot upload to remote site, hence needed to attach in the 100kb limit.

I use 3DS format for nearly all my work like this and don't really have an issue, all you need is to export the 3DS file with preserve texture coordinates checked.

Doug Nelson · #24 10-23-2007, 11:09 AM

It's strange, the texture does seem sharper with the 3DS file.

This is very educational.

creeduk · #25 10-23-2007, 12:35 PM

Yeah I thought it was strange and read them both in side by side, the OBJ is kind of blurred in comparison. I have not had chance to run the other formats but it would be interesting to know which one gives the optimal result.

Dave.Cox · #26 10-23-2007, 04:56 PM

creeduk, thanks for the feedback. The check box "Preserve texture coordinates" is checked by default, and I always leave it checked, yet I still can not get the textures to be included in the file. If I import the 3DS file back into Studio, or into PS, still no texture. I sure would like to know just what it is that I am do wrong.

Doug Nelson · #27 10-24-2007, 06:17 AM

Adobe trumpets the collada format. I wonder how it would compare to 3DS and OBJ?

creeduk · #28 10-24-2007, 09:21 AM

Dave as long as the texture is an external file like your TGA and it is in the same folder as the 3D file then Photoshop reads it with no issue. That has been my finding so far any way.

I made this last night. Didn't have time to texture it, so I used an apple texture from one of my past projects for it. It looks like an illegitimate offspring from an apple and a bell pepper if they mated. I'll try to export the OBJ and upload it tonight. Not sure if Photoshop could handle the texture since I used a shader instead of a bitmap.

Doug Nelson · #30 10-24-2007, 03:13 PM

Should be interesting. I did think on first look that it looked a bit apple-y

That should be easily fixable in PS by cranking up the green a bit.
