Rendering, Constant Color

Lunau

Hi,

In Evolve 2014 you could give a object the material 'Constant'. That made it render as a solid shape with no shadow, texture og light.

A good option if and when I need a 'Masking' layer in Photoshop:

I would give every component it own Constant color and I could use that render to put on top of a real render in Photoshop and then easily pick parts of the illustration with the magic wand tool.

Is there a similar way to assign a material in Evolve 2015, that would come out as a 'Constant'/solid?

Hi Lunau,

Unfortunately this feature is unavailable in our new rendering engine in 2015. However, I have added a request for enhancement to include this in our upcoming release.

Since we cannot disable shadows for global environment maps, it is a little tricky to obtain solid colors. There is a work around for this, which depends on your scene.

1. Make sure you assign solid colors with 0 reflectance and 0 roughness

2. Under environment properties assign the reflection and refraction maps to none

3. Bump up the intensity of the environment map to a higher value like 10 or 15. This usually removes all gradients and adds a white wash effect retaining the solid color because you have 0 reflectance.

4. You can either remove the background map or assign a solid color like black.

The only scenario where this would not work is if you have tiny crevices and areas where the light cannot penetrate even with a higher intensity. You would have to hide the object/part causing this shadow and render the scene.

Thanks
