Problems with a TESR

[Pennyw95]

Hi, today I need some help with my TESR.

 

I managed to get it actually rendering correctly from every angle and to enable blending in order to allow for transparent textures ( for the glass pane).

Right after I got the transparent panes,though, I noticed that some internal parts are not being rendered!

I tinkered with the the main block class, the TE class and the renderer but nothing changes....it breaks sometimes.

 

Here are some pictures: you can see from the Tabula screen how it should render. In-game it's missing 3 legs and the purple floor.  http://imgur.com/fckjD2x,CR8luyo,1WGDeMe

In the second image the TESR is not correctly aligned with the bounding box, don't mind that.

Hi

 

You're probably running into the problem that alpha blended quads have to be rendered in a specific order.  You have to render the furthest-away quads first.  If you render the closest quad first, then when you draw the furthest quad, the depth culling hides it.

This isn't easy to fix.  If you turn off depth culling, your quads render in front of everything, even solid blocks.

If you turn off writing to the depth buffer when drawing alpha blended quads, the result will still look different for

front quad first, back quad last 

vs

back quad first, front quad last

 

You need to sort the quads in your TESR to render the furthest ones first.  So long as the quads don't intersect, this isn't very difficult.  In your case, it might be enough just to render all the non-alpha-blended parts first, then the glass panes second (keep back-face culling on for the glass panes).

Oh I see...thanks for explaining me

 

I'll try to make a separate method for rendering the glass panes in the model and call it later in the renderer first, if doesn't work I'll change the order from back to front (but wouldn't this mean I'd still have the problemi while looking from behind?)

 

Unfortunately I'm away this week, I'll let you know ad soon as I can how it goes. Thanks again

Hey, I did as you suggested and put the glass in a separate render method that I call after the primary one, and all the trims are working as expected, but the thing is still not rendering properly, as you can see in the pics:

It seems the jarInside box is never rendered even if putting printlines inside the method proves it gets executed...

What may I be doing wrong?

EDIT: Updated paste, should be less confusing. Do not mind that renderGlass is not called, my issue is with renderFloor not rendering.

Hi

 

I'm having trouble seeing what's wrong in your images

 

But I suggest to troubleshoot by

1) Render just the solid parts, including jarInside, without rendering the glass

Your floor might not be rendering if the floor is facing the wrong way (or backface culling is on), or your floor exactly overlaps one of the others

 

Once that works;

2) Turn on your alpha blending and render the glass as well, after the solid parts and jarInside.

Thanks for replying

 

The third image shows how the model, opened in Tabula, should render. The first and and the second image show that the jarInside (the model's internal floor) is not rendering.

 

I tried removing the glass and messed with culling already but that simple box just kept refusing to show up.

 

In the end, I solved the problem by removing it from the model class and tessellating it separately, in the renderer class.

So, although in an unorthodox way, my problem is now solved.

 

Thanks for your precious help, I learned alot from you advice

 

 

 

EDIT: One last question: I want to render some particles during the crafting process but after setting up the packet I realized that the particles are invisible if spawned inside the model, the transparent part, but they work if spawned above it.

Is there way to bypass this limit?

Re particles - I think that will be tricky because the particles render after all the blocks are finished.  You would need to draw the particles before the transparent glass, i.e as part of your tessellator instead of as EntityFX particles.  It can be done, but it's a bit tricky (basically - your tessellator would keep track of the EntityFX, move them & render them, etc, instead of spawning them as you normally would.)

That seems a bit too hard for me, I guess I'll stop here..

 

But anyway it works perfectly now, thanks for your help!
