Hey Guys i implemented the Generate Normalmap puzzle for a texture from text.

This works – but if i update my text (normal map gets updatetd too) -> my console shows me every time: Verge3D 2.15.0 pre1 (WebGL 1.0)

After updateing the text for the thrid or fourth time , the whole scene crahses – it it says in the console: v3d.WebGLRenderer: Context Lost.

If i deactivate the normal map puzzle: i can update the text as often as i want without crashing the scene.

I really cant tell whats the problem.

Heres my puzzle setup:

Looks like you are creating big textures and hitting GPU memory limit. We’ll investigate if it is possible to free memory from created textures. Thank you for reporting this!

Hi,

it’s highly possible you have a memory issue. The 2860×1445 size is quite big for the textures. Also, this size is not recommended for interactive 3D. You better try something like 2048×1024 or similar (256,512,1024,2048 width/height values are OK).

Hey Alex. I reduced the size to 2048×1024 as you recommended. Thats a good idea, but it will not solve the problem, that the puzzle is triggered multiple times.

Hi Yuri. I hope you are doing weill. Do you have any news on this issue? Im almost done with my first demo and the last thing thats bothering me is this problem.

In my case the generate normal map puzzle in combination with texture from text puzzle is kind of useless if it cant be triggered more than 2 oder 3 times.

It would be awesome if there was some kind of fix for this!

Thanks

We created a task in our dev tracker. Hopefully we’ll investigate this issue soon.

UPDATE: we managed to fix that. The fix will land in the next Verge3D update.
