Here's the current advancement of the store. I've set up a few boxes already to get a feel of how it's going to look like.
I decided to make my own furniture for the store, so that I can control the size, the poses, the colour, and so on. I've made a vinyl love-seater and have put two conversational poses in it. I'll add a "cuddle" pose and a shadow, and depending on how it turns out, I will consider selling it. For now, it's exactly the right colour and at only 6 prims, it won't overburden the sim.
I've also taken a screenshot of what the building looks like in Blender. I find it easier to align prims, and overall it's faster to build. The downside is that it's a bit more difficult getting a sense of scale. I work with a picture of my land in the background, so I'm not completely out of whack, but it's still a bit larger than I thought. Overall it's less buggy than
SL, and there's no rubber band effect!
