Parallax Occlusion Mapping...

[sgi]

Yes! That solved the problem. Just use
RayLinearIntersectionSM2(aHeightMap, vHeightMapPos, vEyeVec);
instead of
RayLinearIntersectionSM3(aHeightMap, fSteps, vHeightMapPos, vEyeVec);
in
core\shaders\deferred_gbuffer_solid_frag.glsl, line 147
and all problems disappear.
The only difference between two functions is fixed step instead of adaptive step.

Men

you rocks. YOU FUCKING ROOOOCKS !!!

i will try it right now !!

[Deu sex]

-_- it doesnt work, textures with parallax possibilities are all dark.

[sgi]

ok, I check now... they are dark if shader compile failed (there is an error in shader).
...
No - everything seems to be fine to me. What video-card/drivers do you have?

[Blackhand]

This worked for me, well done. It looks like there is only a minor performance penalty for enabling parallax, none of the big slowdowns/crashes I was getting earlier.

[Mina Darsh]

Wow, amazing, it works yes, however, does this mean the game switches back to Shader Model 2 as well?

[Blackhand]

@Hionimi: From what I can see, no. It looks like the two different functions just perform a calculation, one I assume optimized for SM2 and one for SM3.

[CHANCEPHOENIX]

IT WORKS for me too !!!

i thought at first that i was missing something switching from SM3 to SM2 , but ...

I CAN SEE no DIFFERENCE ... AND IT RUNS GREAT.


btw. modified pom is the one from sgi :



anyway , THANX for making this work ....er .... and please do sumthing to activate dynamic lighting/shadows(esspecially for the lantern) IF it"S possible

[Zanderat]

I have the dark shader issue, too. ATI 5770. Oh, Well. Getting closer.

[sgi]

All who have dark surfaces, try to change line 82 (in RayLinearIntersectionSM2 function) from
avEyeVec /= lSearchSteps; //Split up the eye vector into the number of steps
to
avEyeVec /= float(lSearchSteps); //Split up the eye vector into the number of steps
