Explosion with Embergen and ue4
Decided to go back to Embergen after long time, this is day one trying out some nice explosions
Day 3
Edit the Trails, they where whay too big and low resolution. beside that, they were just sprites, exchanged them with a tileable texture and a ribbon. further added another event that creates some flying sparks
Explosion Day 2
only 2 hours time today
Added dust, redo some placing, shading and timings
editing materials
Result of Day 1 in UE4, created first animation sprites Niagara systems and materials. currently facing some shading and sorting issues
Embergen work, created 3 textures, the main mushroom from front and from top, and some side mushrooms
I added some fresnel to the Material so I can blend based on camera angle and clip the side view when viewed from top and the top view when viewed from the side.
this gave me the base atlas_ sheet, vector maps and some mask map
the main mushroom got the integrated flip book motion vector node to soften the flip book animation a bit, so this way I can use a 5x5 1k texture for the big main explosion
the side mushrooms and the flying debris will get a normal simple material.
the niagara systems are some simple systems until now
I split them into 2 systems to deal with some sorting issues ( the small side particles are getting chopped away by the big explosion, to prevent this, I created a second niagara system and compose it inside Sequencer, the integrated niagara sorting is :/
which gives me this texture, I will make it tileable in photoshop and use it as a smoke ribbon for my directional smoke ribbons
I went a bit excessive with the niagara system. This might be a cinematic or unique explosion. for multiplayer games this might be a bit expensive.
I think about doing a biot more passes on optimisations here
created this scene in embergen. a 2048x1024 resolution camera with a high rising pillar of smoke
