Displacement/lightmap issues cont (this time with pics)

[Shinobi]

Well recently I had some problems with lightmaps on my displacements where lighting had these huge circular shadows scattered about...

I made a thread here

http://www.halflife2.net/forums/showthread.php?t=101982&highlight=terrain

and I thought we had discovered the source of the problem, but after adding new terrain and a 2048x2048 normal map to the rock part of my blend texture
the map would crash while loading with this error message

"AllocatedLightmap: lightmap too big to fit in page 535 in 512"

I'm paraphrasing this error from an internet error page since I dont have a compiled version of the map that has this error...

anyways I ran a program called lightmapfix sicne I cuoldnt find the terrain without a base 2 light scale.. The map finally worked and would load but now I get all these REALLY funky shadows.. some of them look like the missing texture checkerboard pattern....

Last thing I should mention is I think the normal map for the rock may have something to do with it... the map would load before I added the texture, even with bad lightmap scales...

here's some screens.. I hope this post is readable, I've had a very long day and very litle sleep

thanks in advance


EDIT: also you'll notice that these errors only seem to occur on the rock portion of the texture

also I just noticed in the texture browser it reads the blend textures as 512 in the hammer texture browser...


it's actually 2048

I don't think you can blend normalmaps.

I don't think you can blend normalmaps.

I'm sure I've seen it done in hl2 maps... I think.. lol

this true?

EDIT: I believe the normal map on the grass works,, can you just not have 2 normal maps in a blend?

update: I removed the normal map in the vmt and the checker pattern is now indeed gone... oddly enough the normal map for the grass seems fine.. even when I disable the grass normal map and only have the rock one enabled it still has an error..

go figure.. oy

the circle shadow problems are there but I suspect it may just be related to the other threads problem

You can have a bumpmap, but I wasn't sure if you could have one for the grass blend into one for the rocks. Seems you really can't.
