Technical Q&A for CG Trader Sellers & 3D Artists

Q1: What are the best file formats to upload on CGTrader?
Ans:
The most commonly accepted file formats are STL, OBJ, FBX, BLEND, 3DS, and DAE. STL is widely used for 3D printing, while FBX and OBJ are best for game assets and animations. It's recommended to provide multiple formats to attract more buyers.

Q2: How can I make my 3D models more sellable on CGTrader?
Ans:
Upload high-quality renders with good lighting and clean backgrounds.
Provide multiple file formats to increase compatibility.
Add detailed descriptions and tags to improve search visibility.
Include well-organized UV maps and PBR textures if applicable.
Offer low-poly & high-poly versions for different use cases.

Q3: How do I properly scale my 3D models for 3D printing?
Ans:
Ensure your model is designed in real-world units (mm or inches). Check wall thickness (at least 1mm for most prints) and use software like Netfabb or Meshmixer to inspect and fix geometry issues before exporting as STL.

Q4: What are some common reasons for CGTrader rejecting a model?
Ans:
Non-manifold geometry (holes, intersecting faces).
Missing or poorly assigned textures.
Incorrect scaling or orientation.
Copyright issues (e.g., using trademarked designs without permission).
Poor preview images that don't showcase the model properly.

Thanks for your time..
