Building “The Tomb of Glowing Lava” Diorama

The Tomb of Glowing Lava

This has been one of the most fun dioramas I have ever built with glowing lava, a plucky heroine and some great new techniques. You can get a free painting guide to glowing lava here. I’ve listed the materials then a quick step by step. Please check out my collaborators – My Mini Factory – they have some amazing designs on their website.

I did a longer version of the video for my Patreon page and that went into far more detail on how I wired the diorama.

Step by Step

First was choosing the 3D print designs. When My Mini Factory asked me to collaborate with them on a diorama, I knew exactly which designs I wanted to use as I had been looking at the Meso American collection by Iain Lovecraft for over a year. They screamed Tomb Raider to me and what could be more fun than a lava filled tomb with Lara jumping her way from pillar to pillar to cross it?

The first challenge was to find a design that would show off the glowing lava whilst sending Lara on a journey, all using the STLs provided. Thankfully, the files included plain floor tiles that I could remix to produce the walls and stone columns I needed. An altar was cut up for the stepping stones and the Toran was shortened to fit.

Once the designs were sorted, I printed everything full size on my Peopoly Phenom using Peopoly Deft resin and the default settings. This is a large resin printer and even the pyramid fitted in one go. All would have been perfect if I had remembered to fill the resin up on the 26 hour pyramid print!

A key feature is the glowing lava and that needed lighting. I used a string of fairy lights with 100 LEDs and a picture frame base to give the effect I needed. The clear Perspex in the frame allowed the lava to really glow from underneath.  I did end up adding another string towards the end as 100 LEDs were just not bright enough though.

Any 3D print is made infinitely better by a good paint job and for this lava chamber I painted the light directionally with a cooler brown from above and a reflected lava glow from below. I also added in fluorescent paint so that the stonework really glowed with light even without the LEDs turned on. 

Once everything was painted, I assembled it on the base. I heat formed transparent worbla for the lava streaming down the walls and to avoid the LEDs behind it being too spotty, I added a diffusion layer from some packaging material. I needed the lava to be crusty and for that I used three types of acrylic texture gel to fill gaps, build up the cooled lava and add a little bit of texture to the flatter areas.

I painted the flowing lava with a mix of model and fluorescent paints. The fluorescent paints are fairly translucent so they needed some extra coverage from mixing with a model paint. I sprayed two layers of each colour to slowly build up from yellow to red.  I then dry brushed a small amount of a darker colour to bring out the texture.

For the lava crusts on the floor of the tomb, I hand painted and dry brushed the cracked shapes. I highlighted every edge to represent the light and the hotter lava. This was time consuming but really makes the diorama come to life.

Finally, I put a fluorescent orange wash over everything, including where the light reflects on the stonework, to really make the lava pop and when that was dry, I touched up the yellow cracks with a fluorescent yellow.

The Toran entrance was painted a stone colour then weathered using enamel washes. It’s deep in a jungle so the green toned everything down.

Finally, I printed a mini Lara Croft and a golden idol for her to steal. I painted Lara in model paints and washes then used Alclad lacquers for the idol.  They both got liberally doused in fluorescent orange to give them the reflected lava glow.  

All I needed to do then was turn on the lights and enjoy as Lara makes her way around the tomb.
