Rensei’s Sketchbook – Actual Time VFX

That may be a fairly cool concept and your outcomes are superior!

Some peeps requested how to do that so here’s a fast breakdown:

Initially I file some movies of the web site I discussed within the earlier put up. I take advantage of OBS and crop out the view so solely the sim half is seen.

Then, export frames from the video. I used VLC as a result of that’s what I had and it was fast sufficient for this check. I’d advocate utilizing one thing else if you would like extra choices and extra fps exported. (I really feel like there’s a quite simple means to do that, or file straight into frames so simply get the concept of what’s taking place and do higher than this hnnn…)

Depening on the size of your recording you would possibly get couple thousand frames so watch out
With all frames exported I take away all fully clean frames as a result of they’re ineffective anyway.

Subsequent I select the sequence I’d like to make use of and get it into Unity.

I disabled mipmaps and set compression to None. These frames will probably be eliminated later and never utilized in sport, however I need to course of them in highest high quality

Unity has a really cool software referred to as Picture Sequencer, which you will discover within the VFX Toolbox preview package deal

After creating a brand new Picture Sequencer asset I import all wanted frames and preview the flipbook

There’s quite a lot of wasted house on there and I can’t be bothered to crop the sequence frames by hand so I take advantage of some body processors:
There’s a bunch of them offered, plus it’s straightforward to make customized ones by utilizing a customized materials to course of the frames. There are some instance shaders offered (like Blur, Rotate, Damaging or HeightToNormal).

Then it’s as straightforward to make use of as every other flipbook ! I used shuriken since I’m working in BiRP atm

It was a enjoyable experiment and the identical course of can be utilized for already made movies or no matter you may get/discover on-line with the proper licensing

Sword slash vfx sketch
The VFX half took couple hours, was fairly enjoyable, particularly since I by no means made it earlier than hah. There’s a lot to doooo

Colors are primarily based on the plasma colourmap, I used it earlier than and I actually prefer it =3=
https://matplotlib.org/secure/tutorials/colours/colormaps.html

Some peeps requested for a breakdown for this so right here it’s:

I’ll begin from the start:

1. Is simply black with some clean slowly scrollng noise. Rotates round it’s Y axis and strikes ahead when emitted. It’s the slowest and disappears first out of the three.
   
2. The glowyone. I’m utilizing the gradient I discussed earlier than. This one is quicker than the primary one and has an extended lifetime, additionally stops spinning half means.
   
3. That is the quickest one and lives the longest. Additionally it doesn’t roate over lifetime. I felt just like the slash wanted some residue up entrance so I added this
   

• Affect traces or scan traces
  (Superb compression) It’s only a quad with polar uv’s and a noise texture scrolling outwards. It’s a Uncooked Picture on Display screen Area canvas so I can apply the invert filter on it.
  
  I simply realised that it was fully pointless, as a result of I really needed to maintain the black traces when inverting the color
  If I did it proper it will have regarded extra like this. OOPS

• Invert colors put up processing impact
  It’s a easy customized PP impact. Like, very barebones easy. I simply allow it for 0.07 seconds with the scalines to make a spicy flash.

Shader "Hidden/Customized/Invert"
{
    SubShader
    {
        // No culling or depth
        Cull Off ZWrite Off ZTest At all times
        
        Go
        {
            HLSLPROGRAM
            #pragma vertex VertDefault
            #pragma fragment Frag
            
            #embody "Packages/com.unity.postprocessing/PostProcessing/Shaders/StdLib.hlsl"
            
            TEXTURE2D_SAMPLER2D(_MainTex, sampler_MainTex);
            
            float4 Frag(VaryingsDefault i) : SV_Target
            {
                float4 shade = SAMPLE_TEXTURE2D(_MainTex, sampler_MainTex, i.texcoord);
                shade = 1 - shade;
                return shade;
            }
            ENDHLSL
        }
    }
}

utilizing System;


namespace UnityEngine.Rendering.PostProcessing
{
    [Serializable]
    [PostProcess(typeof(InvertRenderer), PostProcessEvent.AfterStack, "Custom/Invert")]
    public sealed class Invert : PostProcessEffectSettings
    {
        
    }

    inside sealed class InvertRenderer : PostProcessEffectRenderer<Invert>
    {
        personal Shader m_shader;
        
        public override void Init()
        {
            m_shader = Shader.Discover("Hidden/Customized/Invert");
        }
        
        public override void Render(PostProcessRenderContext context)
        {
            var sheet = context.propertySheets.Get(m_shader);
            
            
            
            context.command.BlitFullscreenTriangle(context.supply, context.vacation spot, sheet, 0);
        }
    }
}

Hopefully that’s sufficient element, it’s a quite simple impact, simply bunch of various components glued collectively

Some current explosion I made whereas attempting to get out of the burnout part:
