OBJ files open fine in Dimensions but not PSD 3D

I'm having issues with downloading OBJ files from sites like Turbosquid and others. OBJ files are all loading with object models that have the same material layers. It's like every part of an object has the same smart object and when you assign a color or texture to one it applies that same treatment to all. Yet when I import the same model into Adobe Dimension each material layer is totally editable from the other. I can change the color or add texture to each one.

This wouldn't be problem, but I'm trying to create some 3d animations with timelines, and since Dimensions can't animate it really does me no good.

Is there a solution to this importing issue within Photoshop that anyone knows about?

one good trick with Obj models from the internet is to open them in Photoshop and export them as a wavefront | Obj... this will clean up | fix a lot of the UV maps you get from cheap sites

Could be something specific with the OBJ files. Regular groups and parts are a different thing from material selections/ groups and depending on how an OBJ file is exported from whatever program, this tagging can get rather messy, as it's used inconsistently across the board. Also check whether the associated MTL file actually contains correct definitions and paths to textures.

Photoshop is an older 3d software and defaults to a different material system than Dimension... which allows you to add | make custom edits even if the model does not have that part

Dimension is for still images only at this point and yes Photoshop has some timeline options but its not a true machinima like Iclone, Unity or Unreal so imo you are using the wrong tool for the job

p.s, the work around I use is rendor Dimension image as a Psd (with my fixed | custom edits) then open that in Photoshop and make the Tpose load the custom textures Dimension made but its a slow workflow

totally understand and that is one workflow option I was looking into. It seems to me that that there are a few Adobe tools that should think about merging or at least linking. I could see the 3D move to Dimensions and add the timeline feature to it. I would love for it to have industry standard modeling and rendering capabilities. Not it's own made up experience. Someone working in other 3D apps should be able to open it up and start working. Maybe Fuse could be the rendering app and Dimensions could be the compositing and timeline editor. That could be a really effective workflow.

It would also be great if the animation experience was similar to both Adobe Animate CC and Character Animate for the same reason of being able to open the apps up and just start working.

Just my two thoughts. My only real option at this point is to start learning apps like Blender and C4D. Neither which I'm really excited about doing. It will be a long process.

the underpinning issue here is industry standard modeling and rendering capabilities = Windows only... Apple Mac just doesn't have the gpu power to walk their talk and Adobe won't dare make any software that doesn't run on some kind of Mac

yes Fuse has very smart design (under the hood) to make those models fit together so easy but easy for the user = complex designs and that is only fine in a small app like Fuse not in something bigger like Iclone... I agree Blender is your best option for a learning app

this tutorial shows you how to set Blender up and what each of the options do

Hi

As a test, I have just downloaded and opened a model from turbosquid without an issue. Each part can be textured separately.

Can you show the 3D panel and layers panel after opening the obj file?

Does the 3D panel show separate mesh components for each part of the model (example below)?

Thanks Dave. Yep I have had some success. It seems to be hit or miss based on the modeler. I have downloaded several models some have no issues exactly like you have pointed out. This thread isn't allowing me to attached a screen cap of the issues. But each layer/material like in your example is the same object name. As if it were a smart object that was copied and not copied as a new smart object. I'm not proficient in a 3D app like Maya or Bender. I'm just trying to do some simple moves of a phone device and play a movie inside of a smart object to show an app animating. Sounds simple, turning out not to be. I really don' want to have to go into full blown production mode

Hi

It sounds like you are not using a specific material file but just trying to assign your own materials in Photoshop to the various sections.

If so you could try this :

Make a copy of the obj file.

Open the copy obj file with notepad (it is just a text file)

Scroll down and find the lines which say usemtl xxxxx where xxxxx is the material name. From your description several materials are sharing the same name so change them to different names e.g. usemtl xxxxxA and usemtl xxxxxB ...etc

Save the file

Now open it in Photoshop and you should get separate materials that you can edit and assign as required.
