is it better to use extruded textures for complex flat shapes then building the shape with cubes?

[whole dew]

in terms of how lag/processing power it takes to render models.

if i wanted a shape thats complex, but on a flat plane.

is it better to use a texture, make an extruded model, then include that into my bigger model?

or would it be better to build the shape out of multiple cubes?

or is practically no difference/would not matter since the hidden sides are culled anyway or something?

like take the attached shape, is it better to make this out of 7 cubes? or with an extruded texture?

(i think i know what extruded textures are, there like how swords etc work, but let me know if this question makes no sence, and I'm wrong about what an extruded texture is)

You might as well just let the game extrude the texture

[whole dew]

well yes in this case, but if i have 2 hearts i want arranged like this is it better to use 14 cubes, or 2 extruded textures

is there a processing efficiency difference?

[maiden gulch]

Use the Import Extruded Texture option in Blockbench

i know that it can be done, what im asking is.

lets say i place 1000 of these in a room in a world.

will making it out of cubes vs extruded texters make any reasonable difference in the amount of processing power that it take to render the 1000 of them?

Making out of cubes by hand can result slightly better performance in some case(using inverted cube technique), but most of the time it's better just do extruded texture. u know very time consuming to build by hand.

If you are gonna place 1000 of those, I am afraid even ingame generated ones will result ppt peformance, and will be even more noticeable to two of the method you ask for, in this case u might wanna consider alt or rethink what you are doing.

pixel art? then stacking it on top of itself? idk

[whole dew]

Im not actualy trying to stack 1000 of them, just a theoretical, if pushed to the limit, which way would generaly be better. (they may both suck, but is there a good enough diifrence that i should prefure one method over the other)

Good to know it wont make to much of a diffrence, and extruded textures will probs be fine.

[lone skiff]

special case i mentioned earlier is the pic above below, where instead of 4 cubes, 2 cubes can achieve the same shape. But even still that just 1 or 2 cubes less than the normal way. If majority of your model can apply that then yes the performance will be slightly better than without using it.

That being said, extrude texture and manually placing cubes are basically the same, or not if u didn't do the optimize way.
as they are both the worse way to make a model, performance drop cuz more faces will have to be calculate.

i don't know how much better but do the built-in generated method as much as you can. For example, if possible you can spawn two heart item and place them side by side so it stack.

how make inverted cube?

[maiden gulch]

An inverted cube is a cube with negative size values

[cerulean oar]

thanks you

[cerulean oar]

how do it, it just makes the cube really weird? did it in the generic model

[whole dew]

allright thank you

[whole dew]

is this done though making the texture on one of the sides transparent? otherwise if the sizes are negative, how can the texture be see though in the middle.

[lone skiff]

the large cube has it top and bottom a transparent hole in its texture.
then a inverted cube, with top and bottom face removed.

[whole dew]

okay, so how are faced removed? is that this uv enabled thing? or is it something else?

[lone skiff]

Don't recognize that screen cuz I am still in slightly older version. I set it as a keyblind.

But yes that checkbox seem like it.

[whole dew]

alright ill give it a try.
