Hi Samuel, are you using parallax mapping technique for this height displacement?

I don't understand. You want to rotate HDRi?

Yes. Rotating the HDRi 360° will change the lighting directions since HDRis gather light intensity from the brightness of pixel colours. Thus normal maps will behave accordingly.

Something like this:

Or simply to change background view:

• Plugin comes with a tiny PBR materials library. Donate to make it grow!

Take a look at these websites for free (CC0) textures: Pixel-Furnace, CC0Textures, freepbr. You can provide link to these sites maybe?

I think you should indicate that we need to open a collection to use PBR materials you provided. People may not find PBR folder you generated easily.

In addition to 'saving, opening and creating' a model, when we "apply all changes" in the PBR material editor, Chromium pops-up and updates the view as well.

HDR images working fine Can we rotate them somehow? That would be cool

Hi Orgelf, marvelous art you're creating, please don't stop

Is there a particular reason you model in SketchUp and not in Blender (especially such complex objects)?

Also do you have a Sketchfab profile? Seeing and navigating around your models in 3D would be amazing.

Check Instant Meshes. It's a great tool to reduce polygon sizes and retopology with lots of features.

It only imports/exports .obj and .ply files but it's free!

Also check this tutorial for how to setup textures afterwards in combination with Blender software.

Check this fresh plugin: Physically-Based Rendering

Unfortunately I've always experienced this freeze issues with high-poly models in SketchUp and i didn't see any improvements to be honest. I can't even import some models (trees for example) without crashing SU to create their proxies for renders yet it's almost instant importing the same objects to Blender.

I don't know if this is a limitation of the Ruby programming itself or lazyness of SketchUp Team.

Can you post some screenshots?

Make sure those components doesn't have backfaces visible to camera. (Check in monochrome mode)

I think it's because GPU rendering is fairly new technology comparing to CPU rendering, so i believe it's just a matter of time that will support every feature like in CPU.

Can you share your texture and opacity map (transparency)?
Here is a working example:

Note that it might not work with GPU acceleration or interactive mode.
Check this for more information about Emissive Material.

Thanks for the details.

Normal map must be set in PBR Material Editor. Does this info helps you enough?

I know what i meant was even though i apply normal map, it doesn't show up in web browser, object looks plain. (When i launch material editor again right after i applied normal map, it shows blank, does this mean it didn't accept the normal map?) Also i made sure it's 1024px etc.

Hi Samuel, interesting plugin, nice to see PBR and Gltf related extensions

But i couldn't operate normal map. And didn't understand where you put those 2 'base color' textures you provided.
Also that would be great if you let normal map strength to be adjusted and option to add metallic & roughness maps as well if possible.

You can enable 'Only in Secondary' option at Material Options.

When enabled, objects with this material applied will only appear in reflections and refractions and will not be directly visible to the camera.

Looks like a 'color space' issue to me and not material. Make sure you enabled sRGB color space in the Vray Frame Buffer. Check this: V-Ray Frame Buffer | VFB

A little fun fact that you might get surprised: US is officially on metric system!

Take a look at below video for an authorized person at the National Institute for Standarts and Technology (NIST) comment on this:

@unknownuser said:

All the units that we commonly use like feet and gallons and so on are actually defined in terms of metric units so it's just a little translation that we do here but our country is actually on the metric system.

I suggest watching whole video but espcially for the quote watch between 0:31 - 1:25

What is your hardware (CPU and GPU)? Are there any displacement or bump map too much? Do you have super-high resolution textures? How you lit your scene, do you have emissive lights?

Try highering the noise limit (denoiser will do this instead, faster)

Also your image resolution is Image Width/Height and not Aspect ratio, are you aware what you're doing there?

It depends on your scene, what are you rendering, can you share some screenshot?

You can use Irradiance map + Light cache combination if not already. Try using 'denoiser' to get rid off noise instead of adjusting other parameters much.

Make sure that shape is set to 'Sphere' and not 'Hemisphere'. (Check this)

Also note that your HDR image might be just hemisphere or panoramic, so try different one in that case.

Try reverting to default settings and test. (See bottom left icon for default settings)

Why don't you just get lycra fabric dimensions and design according to it? (it'll be printed before stretched, right?)

If you designed stretched3D shape (the canopy), i think it won't be possible to unwrap/unfold without weird cuts.
Example:
