multiple textures rendered

Posted August 20, 201312 yr

hello people,

I'm trying to code a new flower pot since i want to have my own flowers in it.

but i stumbled upon an issue, the texture of the flower rendering inside of the pot is rendered more than 1 time.

width=800 height=449 http://spenk.bplaced.net/images/2013-08-21_01.35.40.png[/img]

(default pot left, my pot right)

here is my render code.

the same happens with saplings.

i hope you guys can help me with a fix, this issue has been delaying me for 3 days already.

thanks in advance.

i have done multiple debug tests the results were as following,

i put renderStandardBlock inside the renderWorldBlock void, it was rendering without problems.

i removed all remaining code in my own render void but left the flower pot render code, the flower pot rendered as usual without problems.

but when i added a piece of code to render a red flower in it, it started to bug the texture again.

it seems like the overlapping textures are bugging eachother ?

is there any way to solve this?

i got my problem solved by moving the inner walls of my plantpot because they were colliding with the new rendered flower

        renderer.renderFaceXPos(block, (double)((float)par2 - 0.5F + f4), (double)par3, (double)par4, icon);
        renderer.renderFaceXNeg(block, (double)((float)par2 + 0.5F - f4), (double)par3, (double)par4, icon);
        renderer.renderFaceZPos(block, (double)par2, (double)par3, (double)((float)par4 - 0.5F + f4), icon);
        renderer.renderFaceZNeg(block, (double)par2, (double)par3, (double)((float)par4 + 0.5F - f4), icon);

INTO

        renderer.renderFaceXPos(block, (double)((float)par2 - 0.5001F + f4), (double)par3, (double)par4, icon);
        renderer.renderFaceXNeg(block, (double)((float)par2 + 0.5001F - f4), (double)par3, (double)par4, icon);
        renderer.renderFaceZPos(block, (double)par2, (double)par3, (double)((float)par4 - 0.5001F + f4), icon);
        renderer.renderFaceZNeg(block, (double)par2, (double)par3, (double)((float)par4 + 0.5001F - f4), icon);

How Can I Safely Play an Old Version of Minecraft?

Yeah, you can safely play Beta 1.7.3 using the official Minecraft Launcher. Just create a new installation, pick the old version from the list, and set a separate game directory so it won’t interfere with your current saves. The main compatibility issue is that old saves may break if opened in newer versions, so always back them up.

Mod for world Templates

No, there isn’t a dedicated Forge mod for world templates in 1.20.1. Your options are to use datapacks for custom worlds or run the Fabric mod through Connector.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)
