[1.12.2] Problem with OBJ Model rendering

[Darth]

Hi gyus. I have really strange problem with model rendering.

 

If you look at the model at the first angle - everything is fine, but if you look under the second... I use TESR for render model. All code u can find above:

Is the model going to be animated? If not dont use a TESR use the normal model system, forge adds support for obj models.

[Darth]

Model must be animated, so without TESR it's impossible to make. I want this eye will always been rotated to the player, if u know another way to make this please say it.

This is not how vectors work. You need to get an angle between your vector and the default unitZ vector to get the rotation you need to apply around the Y axis.

 

As for your direct issue - you must bind the TextureMap.LOCATION_BLOCKS_TEXTURE before rendering your TE otherwise the last bound texture is used.

[Cadiboo]

you should probably also te#getWorld#getTotalWorldTime() instead of your timer variable. If you need even more accuracy you can also add the partialTicks to the world time.

 

You might want to take a look at https://github.com/Cadiboo/WIPTechAlpha/blob/fc508e4dd439603888ca2caf08c0b871372764d4/src/main/java/cadiboo/wiptech/client/ClientUtil.java#L776-L801 for the trigonometry and at https://github.com/Cadiboo/WIPTechAlpha/blob/fc508e4dd439603888ca2caf08c0b871372764d4/src/main/java/cadiboo/wiptech/client/ClientUtil.java#L247-L292 for my use of it

Problem was with rendering, not with trigonometry, but thanks anyway.
