[SOLVED] Render texture layer transparent

[yooksi]

Is there a way to render a texture layer transparent, even though the texture itself is not transparent? This would really help me in reducing the amount of model files that share almost exactly the same properties. Every time I create a new item variation that has an extra layer, I have to create a new model file for it, and since it's a bow, this means it has to come with three more pulling models as well.

Hi

 

Do you mean transparent as in "it has holes I can see through" - like glass pane, or as in "I can see other things through my textures" - like ice? 

In general the answer is 'no' except in some special cases.

 

You could consider using a dynamic item model to assemble your item from pieces, depending on what type of item it is.

This tutorial project has some examples of that, which you could adapt with a bit of effort.

see MBE15 - you could modify the quads on one of the layers to have a different texture depending on which item is being rendered.

see  also MBE05 for a similar approach combining models together.

Thanks for the reply, I will take a look at your example in a moment. I have a feeling though that you're talking about blocks, while I am thinking about items. I know that blocks can have translucent textures, but can items have them too?

Hi

 

Yes items can be translucent too, for example try holding the block of Ice in your hand (ice, not packed ice).  Admittedly, I've never tried to make a translucent item so there may be a trick to it I don't know about.  It might be as simple as making sure your item texture has an alpha channel with reasonable values in it (i.e. alpha blending may be enabled for all items) - to be honest I'm not sure.

Item-items can't be transparent as far as I know.

 

Putting alpha value pixels just causes the engine to perform a clip on them (values above 0.5 are treated as 1, value below as 0).

ItemBlock

s are rendered in exactly the same way as regular

Item

s, including the ability to use translucent textures.

 

You can see an example of this here.

Then it's changed from when I last fiddled with transparent items

I was manage to accomplish what I wanted with a custom item model class, thanks to your example on GitHub. Marking this thread solved.
