[1.7.10]Rendering Custom Rendered Block - Alpha Problem

Posted October 14, 201411 yr

Hello, I am making a pipe that has edges that are opaque and the middle of it is translucent. I have the middle are tinted blue, but still translucent. I am using tessellators by the way. My problem is that it is not rendering some pipes that are behind other pipe. Basically I experience the bug depending on which of the two blocks was placed first. Does any one have any suggestions. All help is appreciated, Thank You!

Don't be afraid to ask question when modding, there are no stupid question! Unless you don't know java then all your questions are stupid!

Can any one please help, I need my block to do the opposite of what the vanilla semi transparent blocks do. Example, you cannot see other adjacent ice block when looking through on. I need to be able to see the pipe when I look through the semi transparent parts of the pipe.

The problem is a common one in alpha blending, i.e. it depends which faces you render first. In your case, you probably have depth culling on, so if you draw the closest face first, the furthest face is hidden (culled) and not drawn at all.

The best solution is to sort your faces so that you always draw the furthest faces first. Alternatively you may get acceptable results if you turn off writing to the depth buffer using GL11.glDepthMask(false);

See here for some greater explanation

In your renderTileEntityAt method, try putting GL11.glDisable(GL11.GL_CULLING);

Quick question, is your pipes connections rendering properly? just curious, because the way I am doing it in my mod uses a lot less code for the rendering. Looks like you have followed ScratchForFun's pipes tutorial.

I ask complicated questions, and apparently like to write really long detailed posts. But I also help others when I can.

Sorry for the delay. I have already tried adding that, and that produces a weird line artifact, and yes the pipes do render correctly renderer correctly, I plan to condense it down a fair bit. I was only trying to learn how tessellators work because I have never worked with them before.

I'm not quite sure what you mean by "weird line artifact" explain?

And have you tried enabling GL_CULLING where I said to, then disabling it again at the end, just before GL11.glPopMatrix(); so that you enable it, render everything, then disable it again?

I have just noticed something. You don't have a GL11.glPushMatrix(); and a GL11.glPopMatrix(); How is this working without that? Before you start anything with GL11, start with GL11.glPushMatrix, and when you have finished, end with GL11.glPopMatrix.

I guess the method that calls the render method must call it for me, I had no idea that I forgot to call push Matrix and pop Matrix, thanks for catching that and by weird line artifact I mean it is similar to the artifact that you get when you have z-fighting.
