Here is the blender model:
And here’s the best result I can get in unity (urp 2020.3.22f1):
Note, this is with scene lighting enabled and some post processing is done, also in blender all textures are 4k and properly exported.
this is the best result I can get in unity, I’ve tried all shader options including the Autodesk ones, and this current result is achieved using the universal pipeline Autodesk interactive shader.
I don’t expect everything to be exactly as it is in blender, just something that makes the colors right and makes the normal map on the rubber part of the camera’s body lighted correctly and more visible.
what can I do to achieve a better result?
Hi, I suggest switching to the URP Lit shader.
You can try these steps to make it closer to Blender’s result:
-
Make sure you enabled ACES Tone Mapping in URP.
-
Output the “Sun” (position) in Blender to URP (You may need to readjust the strength)
Seems that you are having 2 directional lights (with shadow) in Blender, but URP supports 1 only.
- Make sure the PBR material settings in URP matches Blender’s. (Albedo, Metallic, …)
You can adjust the normal map strength in Lit shader.
Note: Blender uses “Roughness” but URP expects “Smoothness”.
- Adjust environment lighting.
Seems that Blender is using a default background (Hex RGB: 404040), you can try changing the “Ambient Color”.
- Add suitable amount of SSAO.
Try to achieve the shadow that appears in the gaps.
(Ignore this if you would like to use baked lighting).
- Add a reflection probe for the lens glass.
The glass requires reflection and refraction (which URP doesn’t have). You may need to use semitransparent instead.
Or you can create one with shader graph (but I think it’s not physically correct)
- If possible (no need to move the object and lights), you can bake indirect lighting.
Or upgrade to Unity 2021.2+ and use Enlighten GI. (can move the lights)
