Mirror problem

teechurz_7c41d96282

The rearview mirror on the car in this scene didn't come with a mirror texture, so I gave it one and the resulting image is less than good.  After looking at it in wireframe mode, I can see that the mirror surface is a result of the structure of the mirror.  (It follows the triangle-shaped faces.)

I've tried messing with the geometry editor in Daz, but it only lets me select it and if there's anything else I can do, I'm not aware of it.

Any suggestions for getting an actual clear mirror image out of that mirror?

You don't need any texture map on a specular surface in this case, e.g. a mirror.... Just set Metalicity to 1.0, set Angle to 15 ~ 30, on mirror's surface.

Thanks for your input, but I guess I mispoke.  I didn't put a texture on it, I used the polished aluminum iray preset which already has the settings you described above.  

The reason for the weird result is the surface itself.  I attached a "hidden line" version of the mirro and you can see why.  I have a feeling the mirror on your car is a nice uniform surface, unlike the one on the car I'm using.

I'm wondering what would be the best way to overcome this problem... if there's a way at all.

Oh.. such a topo... It seems not a Daz store product. The attached is mine.

I don't have similar item but you may try with different Angle Values... or cut that surface with Geometry Editor, and send it to Blender for a remeshing.

I thought about trying to send it into Blender, but my knowledge of Blender is limited, to say the least. 

Any tips?

You could just fix it in post.

Add a plane primitive in DS, just in front of and just large enough to cover the mirror surface, and apply your mirror texture to that. Re-render, cut and paste.

Have you tried setting different values of Angle... it still didn't work ?

Anyway, if you want to remesh the mirror in Blender, try these steps:
- In a new scene, load the car. With Geometry Editor, select the surfaces of Mirror only, Ctrl + /, Delete Selected Polygons. Export the mirror to OBJ and Import it into Blender. (ss1 ~ 2)
- Use QuadriFlow Remesh to remesh the mirror. Export the mirror to OBJ. (ss3 ~ 4)
- Import OBJ into DS, the scene you're making, add SubD as you wish and parent it to the Car. Hide the original mirror surface and test the render (ss5 ~ 6)

Another In-Post solution... (no plane)

• Do your main render
• Put a camera in the wing-mirror
• Do another render using that cam
• In [image editor of choice] open both files
• Select/Copy R2 into R1
• Position R2, then muck about with cropping/sizing/skewing etc
