Its decent, with some work it could be great. For the rocky second pic - use less of the models and create some of your own displacement geometry for those rocks.

Oh its based on the lambda complex from HL1. I was able to tell from teh screenshots alone which means its a good recreate.

Yes, I got the impression I had done something wrong.

You are right, I had selected all 6 sides of the cube when I created the wall displacements, instead of just the front side.

I?ll have another go at it.

If I can get the displacement right the file size will come down allowing me to add some more detail and more features.

No offence taken. Your points are helpful and valid.

Thanks.
