graphics with high resolution on cylinder - but low resolution on bottle

[j�rg_4563]

Hi everyone.

Maybe someone got a hint for this:
I created a bottle in Illustrator, exported it as an obj and imported it in Dimensions. When placing a high resolution png graphic on it the rendering is generated in a low resolution (the preview is also pixelated). 

When I place the same png on a cylinder or a bottle taken from the standard 3D models of Dimensons the rendering and the preview is perfect.

After hours of futile attempts with various model scales, recreations and graphic adjustments, I have not found a solution. What do I need to change?

In attach you can find the obj of the bottle.

the attach failed somehow...

Try to Generate UVs for imported object from ilustrator... then place decal. 

Adobe Dimension uses polygon-based mesh structures for its 3D models. Here's a breakdown of how mesh structures work in Dimension and what kinds are supported: May be that can be a reason. 

Mesh Structure in Adobe Dimension

• Polygon Geometry Only: Dimension supports only polygonal meshes. It does not support NURBS or curve-based geometry.

• Editable Basic Shapes: You can use built-in customizable shapes like cubes, spheres, cones, and cylinders to build geometric structures. These can be resized and combined to form more complex compositions.

• Imported Meshes: You can import external 3D models in formats like .OBJ, .FBX, .STL, .GLTF, .GLB, .SKP, and .USD. These models must contain polygon geometry to be compatible.

• Native Format (.DN): Adobe Dimension’s native format preserves mesh details, materials, and decals for reuse across projects.

Thanks for the input.

I tried to import the Illustrator generated obj in blender to generate a polygon-based mesh structure but it failed. Dimension can import the generated obj and stl but the graphic still couldn´t be palced in high resolution.

Maybe there is a way to generate polygon-based mesh structure in Illustrator?

No, it not possible unfortunately. You can try to export different formats 3D files from Illustrator but not customize mesh. One of the solutions is to export PSD file from Dn  and correct resolution of rendered image.  

Here is discussion about this problem:

I have now circumvented the problem by using the standard ‘cone’ model to curve the label in high resolution in the appropriate view and inserting it using Photoshop.

However, the question remains:
Which app can be used to create an obj file that is completely suitable for Dimension?

[Ares Hovhannesyan · Accepted solution]

To bypass these problem use apps that can export Polygon Geometry Only: Dimension supports only polygonal meshes. It does not support NURBS or curve-based geometry. IMHO that can be a solution. In the range of Adobe products you can try Adobe Substance 3D Modeler. (only for WIn).
