Do you have 3D files of your product but you can't use them to create nice images of it?
We can help you with our rendering service: we can create photorealistic images starting from your 3D files (in STEP format).
PS: a detailed 3D model is key when it comes to photorealism. If your model is very different from the real version of your product, textures application and lighting won't help much to make it photorealistic. We offer advanced 3D modelling service by the way, so if you need a detailed and precise 3D model you can ask us to help you out.
