reduce directx level on texture

Hi, Ive made a grassy displacement. It looks great but there are big clumps of grass sticking out from it. I know its supposed to be like this due to the direct x level I have running, but is there anyway of reducing the direct x level of a displacement texture?

I tried to make the displacement a func_detail (which allows me to limit the max direct x), but this causes errors.

Does anyone have any other ideas?

thx

There are supposedly other textures which will look just like the ones
you've used, that don't have the automatic folliage generation. So said
one of the valve guys on VERC, anyway. Failing that, you could look at
the material's vmt file and create new ones using the same base
texture, but without the "%detailtype".

ok thx
