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"

make similar postprocessing effect with translucent material.

Hi, everyone!

I want to use translucent plane that has same effect like post process.

(In my game, in certain area, I have to use that translucent plane instead of postprocess, therefore both effects should have same results.)

However, I can't make same effect with translucent material. You can see my picture below. Red color looks much darker with postprocess..

How can I get same red color with translucent material? What am I missing here?

Thank you in advance.

Hello 정강,

I was able to create the effect you wanted please download and watch the video at this link:

@Ed Burgess

Thank you for your kind video, but I couldn't make the effect I wanted. as you can see in my image above, I want simple shader like fog post processing effect which uses linear interpolation.

I think using modulate blending mode can't make the same effect, as it's result is 'source color x target color'.. :(…

Hello 정강,

I'm sorry that the video I posted wasn't what you were looking for. I updated the material to create a fog like effect that uses linear interpolation to blend between scene color and a vector parameter. The material was also changed to use translucent instead of multiply. Here is a picture of the graph:alt text

Here is also a screenshot showing you the effect applied to a plane if front of the camera. If you want to adjust the fog distance use the scalar parameter plugged into fade distance in the depth fade node!
