I've created a Turbo Model Thingy with techne (if you don't use techne that's what it's called). I tried using export as>Java but it didn't work, it just rendered a cube.

How am I supposed to render a cone? (I'm making a Geyser but I want a model for it)

I'm assuming that you can't render a Turbo Model Thingy?

All I know about this is that there is an unofficial release of "TurboModelThingy" mod that is required for a TurboModelThingy to render. I am searching for a version for 1.7.10, I only found one for 1.7.2.  I don't know if it will work with 1.7.10. The video will help a little.

 

A cone? Cone like "a round cone"? ROUND?!!

BURN HIM!!!

 

Maybe Techne can only export cubes to java. I would try to export your model as an obj file. If thats not possible you can use a software such as Maya or max3D to create an obj file.

Keep in mind that my mod is still in 1.7.2-I have no idea how to update, and I'm not sure if obj files work in 1.7.2

1) Update to 1.7.10.

2) Wavefront model still work in 1.7.
