Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Emissive materials are not rendered?

As you can see in the two images below, I have a SceneCapture2DComponent with a white and black cube in front of it. This scene is then displayed on the box to the right using RenderTargetTexture. What I'm trying to achieve here is an image with only the cubes and no background. And it works: alt text

Except when I use Emissive Color on the white cube like this: alt text

This is what my material with the RenderTargetTexture looks like: alt text

What am I doing wrong here? Why does the emissive material disappear?

Hey LEMMiNO,

I am a bit confused at what you are trying to do because it seems you are masking out the emmissive material properly which is why the cube disappears with the material set up.

Would you mind elaborating on what your overall goal is with this approach?

Thank you,

Andrew Hurley

Basically I want the cube to appear even if it has an emissive material applied to it. Just like in the first image. A real example would be if the cube instead was a lightbulb. The lightbulb would have an emissive material to make it shine and I would like for it to appear just like a non-emissive (base color) material would. I hope that makes more sense.

Is this what you are trying to achieve?

Emmissive Material Set Up alt text

Emmissive Material on Sphere alt text

My next question would be, are you trying to render this in a custom depth? I am just a bit confused as to the inclusion of your RenderTarget addition?

Cheers,

Andrew Hurley
