Ive been trying for about an hour now and have looked at the tutorials on places such as WoT. I cannot get Gmax and I have no idea where to start in blender. I need help....
I'm just now getting the hang of it myself. For what it is worth, I tried on 3 separate occasions to get started with gMax and Blender. Each time I started and failed. It usually ended up with a splitting migraine, Tylenol, and a Pina Colada to call it a night. Finally, I managed to make a flat plane, visible from one side only, in gMax that I could use for painting on the sides of bridges. I was never even able to make a simple box in Blender. Then, I made a squat little cylinder that I was able to texture and use as an attachment mesh for an End of Train light on some cabooses I was reskinning. Ultimately, I was able to get my foot in the door on gMax and I managed to make a primitive boxy grocery store, then a stupid little flatbed car to prove to myself I could do it using the WoT tutorials. Ultimately, gMax helped me get the hang of 3ds Max, and now I'm using that, although I can hardly say I'm "off and running" with it..... more like "still stumbling along".
For what it is worth, gMax is the free "baby brother" to 3ds Max, and is a great place to start if you want to eventually go that route. What I heard of Blender, it has more powerful features and can export better models (normals mapping and such), but PEV has a new gMax exporter that I believe can do them too. I was NEVER able to get into Blender.
I'm nowhere NEAR confident enough with what I am doing to teach (the blind leading the blind), but I can say this: If you want to create content, stick with it. Expect failures. We need our failures to learn from. If you persevere, you WILL get the hang of it. DON'T set out to make a boxcar. Start simple with a building or something. (Something boxy, not something complicated!!) Get your head around one of the programs with simple objects, then move on to the boxcar. It is the small successes that will push you on to bigger and better things. Try to make something big, you will fail big, and give up.
Once I felt I had the hang of it, I moved on to make my caboose. Wow, I over-reached in picking that for my first real piece of content! I got a lot of helpful advice and a little modeling help, and it is now available in a beta form, but I still have a lot I want to do with it. I also have a corrugated gondola that I need to upload, and I'm working on a new car as well. I feel pretty good with what I know, but I also know that I have a LONG way to go.
Maybe one of the more prolific gMax creators can reach out to you and give you a hand...... good luck and I hope to see good things from you!
