Error opening half_life_crate/firstcrate.mdl: No such file or directory
To ease up the process, don't list long directories in the script. Keep all of the files related to your model in the same folder so it knows where to look. Also if you do that, you can compile anywhere. Automatically, QC scripts will look for resources in the same folder it is in. Anything else will get lost unless you type out a long directory like C:/users/rimrook/documents and setting/desktop/hl models/crate/etc/etc/etc... you get the idea.
The line that says
$modelname "half_life_crate/firstcrate.mdl"Should say
$modelname "firstcrate.mdl"Isn't that easier? :3
When you compile, it'll put the MDL file in the folder, then copy-paste it into your HL models folder for use.
I'll be buzzing around this thread from time to time. ^_^
EDIT: Wow. pays to read a bit.
Anyway, your new problem can be solved by using a "Cycler" entity, not cycler_sprite or the env_sprite entities. The reason it crashes your HL is because HL is looking for animations, hitboxes, AI, and all that stuff. Cyclers don't care. I've had that problem a few times, although I don't know why monster_furniture works with some models not with others. If it persists, send me your model and files.
