Thanks so much, especially for fixing the grid align bug. Makes a huge difference. Fantastic.

Yes, in order to see the updated OBJ format you will have to republish your models. We are looking into ways to retroactively adjust OBJs, but have not released anything yet.

I'm assuming this is the case, but will we need to republish objects from within Blocks to see the updated UV properties reflected in the OBJs?

Thanks for all of the questions! I will answer them in order:
- Additional environments are definitely on our list for consideration but no guarantees quite yet. In the meantime, you can use your development console to change the environment color. Open Blocks, type ctrl+d, and then type "env black" to get a black environment. You can also use RGB color values, like so: "env 1.0,1.0,1.0"
- You can definitely insert multiple reference images. Just repeat the process for each image you want to import. Once you import them, you can grab move and scale them with the grab tool.
- We hear you on the idea of locking to a single axis! It is also on our list for consideration but no firm plans as of yet.

I hope this helps!

But thanks for the application. ^^

Please, could put the possibility of blocking an axis, to be able to model from an image without my pulse interfering.

Excuse my English, I speak through the google translator.

Is it possible to have two reference images and have those selectable so that we can align them and build an object around them?

Great to see ongoing improvements! Keep it up.

Any chance of you guys implementing different environments in the future? The current one makes everything so bright, with my eyesight I can't see what I'm doing! A much darker or night time scene would help a lot, or just plain boxes and let me select the colour from the palette for the surrounding colour.

And right back to let you know 1.0.5 is now live again, and the update issue is resolved!
