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"

BumpOffset does not work


I want to have a material, which looks like this (ignore the lights and lightning): alt text

I have an height-, normal- and colormap. So this should be everything for nice normal or parallax mapping. The material shader looks like this. Height ratio is 0.05 alt text

and the resultat is this

alt text

No depth!! What I'm doing wrong? Everyone do itin the same way. Here is my heightmap: alt text

Hi Miauski -

It looks like you need to adjust your reference plane to 0 instead of 0.5. The reference plane adjusts what the shader uses as its zero point; so with 0.5 as the plane measurement, that means 1 (or white in your texture) is pushed forward by .5 and anything below 0.5 along the grey scale will be pushed in. From the image you are using as reference, it looks like using 0 and having the 1 pushed further out would get you closer to replicating the effect you are after.

You could also try the new POM Material Function developed by Ryan Brucks, you can read more about it here:


Thank You

Thank you very much!! The fault was the reference plane :)
