You can render whatever you want for you. You may just not post it in the Mecabricks rendering section if it doesn't bring anything to the 3D model.

Quick render of the new materials Speckle and Glitter.

Material update is now available. This image has been made only using Mecabricks and the online render mode.

@Cowboy123 It is not a time constraint, this is more how visually appealing it is. It must bring something to the 3D model even if it doesn't have to be a masterpiece.

I have been designing this whole rendering system so trust me, it is not complicated to figure that out.
Server storage is not infinite as well and remember that someone is paying for it, and that person is me.

@ApocalypticBrick That is it. You can render images in the workshop. No problem with that, but please don't post every single one here in the model presentation. This section is really to show your best work and images that are interesting.

@sonic232 Yes, I am the creator of Mecabricks.

Regarding the part dropbox, I did not delete your files but if another admin did, there was probably a good reason. For example your texture file for 973pb1906 doesn't not comply with the Mecabricks design rules. Please read these articles:

Please sto re-uploading the images I deleted. As explained previously, Mecabricks is not an image hosting platform. Only upload images with some work put into them, otherwise use a service like flickr or imgur and post the link here.

They remain single element and therefore it is still not possible for users to change them using the material tab. It is intended to give more options to part designers and decoration makers.

Only to use the new features. Overall it will be very similar.
I will document the changes when it will be ready.

Test of a multi-material element with individual controls per material. This will be available once the Mecabricks material system will be upgraded.
