All I have to say right now is that I found out the 3d skybox and Portal are not 100% compatible - which makes me sad, as my skybox is really cool, and I don't want to have to ditch it :(
Thanks to Etset for welcoming me and giving me some good advice on posting.
Some friends and I are making a map pack which I believe will both challenge and entertain Portal players for quite some time. I will release further details as we complete each map.
Questions I asked that got answers
This section contains questions I have had to ask the community to figure out, and hopefully it will help some other poor soul who is banging his head into his keyboard over one of the same problems I was having.
- Q: Why is it that when I look through a portal my 3d skybox overlaps the 'real world'?
- A: That's just the way the Source engine works... they didn't plan on people having 3d skyboxes in Portal maps.
- Q: Why is it that sometimes textures I put in have the tendency to turn pitch black and not light correctly?
- A: Using a model texture on a brush tends to cause problems like this. Either replace it with a non-model texture, or make a copy of the texture's vmt and change the parameter inside from "vertexlitgeneric" to "lightmappedgeneric". Then save it with a new name, and use that named version as your texture instead. If you use this method, don't forget to pack the new .vmt in with your bsp if you ever distribute your map.
