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 material on static mesh does not emit light

Hey there,

i've modified the green wobble material. see screenshot Material Editor

I've created a BSP mesh and converted it to a static mesh, see combined view (lit and lighting only) StaticMesh_Combined_View

As you can see, there is no light emitted. to double check my material i've created a BSP sphere: BSP_Sphere_Combined_view You can see that it does emit light. Did i do anything wrong? My static mesh is set to use emissive for static lighting.

Any hint?

Best regards, Manuel

Hi!

I think color intensity is very low. Try to change your multiplying from 0.2 to 2 or higher.

Hello Kriech0r,

Thank you for the post. to expand on what svv3dUDN said I have included a couple of images.

The first shows which node needs to be modified in order to increase or decrease the amount of emmisive light from the material.

The second shows a comparison of three different values in that field. The far left material is set up the way that you have yours, in which I multiply by .2. The second has the multiply value changed to 1 to simulate no changes being made to the emmisive light value. The far right material has the multiply value set at 15. You can see that by comparison, multiplying the value by .2 (or 2/10 in fraction form) actually divides the emissive output making the material appear less bright than the original value. Using a positive number for this value will give the results that you are looking for.

alt text I hoped that this information was helpful,

Benjamin Hyder
