Is there anyway to transform a ROBLOX map into a HDRI image?

[Jrelvas1]

The issue is pretty simple, i want a special lobby in my game which is meant to load fast, so the map in the background will be just the sky itself.
I’ve already built what i needed into a ROBLOX map, but, is ther any way to convert it all into a HDRI image?

Creating new and fresh Skyboxes

This tutorial will explain how you can convert HDRIs (High Dynamic Range Images) to skyboxes for use in Roblox using Blender, however any other 3d software is capable of doing this. Eventually, we might get support from Roblox with actual HDRIs, especially with the Future is Bright update, but for now this is the way to go. I warn you, this is a long procedure but I added some files at the bottom to make things more simple. However reading this is very useful to understand many things. What is …

What I would do is export the game map (Provided it doesn’t have smooth terrain, since it gets a bit funky when exported), and then render a HDRI externally, and follow the thread above.

Yes, i did look at it, my problem is that i want to generate the HDRI using my ROBLOX map, is there any way to do it?

Export your map into obj and try it that way?

[Jrelvas1]

But i export it to obj, the colors and textures are toast

[uJordy]

Do they appear or is it the environment (lighting)?

[Jrelvas1]

I don’t know, i have no experience messing around with .obj files

An alternative to exporting the map, could be to capture 6 1024x1024 images (Since that’s currently the max size that you can use on Roblox) from within studio, rotating the camera around a point to make sure you have all of the faces correct.

Example (I haven’t tested this yet):

Set the studio emulator to a custom 1024 x 1024 resolution with the physical scaling setting set to “Actual Resolution”. From there you’ll need to change the camera CFrame so that you get 6 angles / CFrames which can match a skybox. Then you can use the screenshot tool from within studio to take the screenshots.

Show me a screenshot of the exported map in your modelling software eg. Blender or Cinema4D

[Jrelvas1]

blender is not able to open .obj files

[uJordy]

I’m sure you can, you need to import instead of using open.

You can on both common versions of Blender, 2.79 and 2.8.

Blender just crashed.

Try once more, if its still the case, then your game may be too big for your computer to handle.

[Jrelvas1]

So, my map is so big that my overclocked i7 cpu and gtx 1050ti gpu can’t handle it.

It just loaded, but it’s just a cube

[Jrelvas1]

Actually nevermind, the map is right above it

I will use this idea instead, but i will need guidance, because i’ve never built a script that changes camera positions.
