Toon Grass Auto-Blending

admin — Mon, 14 Aug 2023 14:17:40 +0000

Something that bothers me about grass are the hard edges at the roots. I'd seen some pigmentation solutions which were tedious, so I created a shader that can blend the grass with the terrain automatically. The cel shading look of my project meant it would be a litle more complicated than usual. I opted for Amplify Shader Editor to speed up the process.

Was mich an Gras stört, sind die harten Kanten an den Wurzeln. Ich hatte einige Pigmentierungslösungen gesehen, die sehr mühsam waren, also habe ich einen Shader entwickelt, der das Gras automatisch mit dem Gelände verschmelzen kann. Durch den Cel-Shading-Look meines Projekts war das etwas komplizierter als sonst. Ich habe mich für den Amplify Shader Editor entschieden, um den Prozess zu beschleunigen.

Una cosa che mi dà fastidio dell'erba sono i bordi netti alle radici. Avevo visto alcune soluzioni di pigmentazione piuttosto noiose, quindi ho creato uno shader in grado di fondere automaticamente l'erba con il terreno. Lo stile cel shading del mio progetto rendeva il tutto un po' più complicato del solito. Ho optato per Amplify Shader Editor per velocizzare il processo.

Both the terrain and the grass needed to use the same lighting, using a toon ramp.

Sowohl das Gelände als auch das Gras mussten mit derselben Beleuchtung versehen werden, wobei eine Toon-Rampe zum Einsatz kam.

Sia il terreno che l'erba dovevano utilizzare la stessa illuminazione, utilizzando una rampa toon.

To grab the terrain colormap, I went straight to the terrain data and stitched the splat maps.

Um die Terrain-Farbkarte zu erhalten, habe ich mich direkt an die Terrain-Daten gemacht und die Splat-Karten zusammengefügt.

Per ottenere la mappa dei colori del terreno, sono andato direttamente ai dati del terreno e ho unito le mappe splat.

          for(int m=0;m<grassmaterials.count if tex0 tex1 tex2 tex3 tex4 tex5 tex6 tex7 splat1 splat2></grassmaterials.count></terrains.length>

The terrain coordinates had to match the shader.

Die Geländekoordinaten mussten mit dem Shader übereinstimmen.

Le coordinate del terreno dovevano corrispondere allo shader.

Since I am using custom lighting, it was necessary to capture the normals of the terrain.

Da ich benutzerdefinierte Beleuchtung verwende, war es notwendig, die Normalen des Geländes zu erfassen.

Poiché sto utilizzando un'illuminazione personalizzata, è stato necessario acquisire le normali del terreno.

        captureCam.orthographicSize = size.z;
    }else{
        captureCam.fieldOfView=60;
    }

            }
            captureCam.Render();
        }

...

captureCam.enabled=false;
}

To sync up the terrain and grass materials, I checked on update, if the main material's CRC had changed.

Um die Gelände- und Grasmaterialien zu synchronisieren, habe ich bei der Aktualisierung überprüft, ob sich der CRC-Wert des Hauptmaterials geändert hat.

Per sincronizzare i materiali del terreno e dell'erba, ho verificato l'aggiornamento, se il CRC del materiale principale era cambiato.

2.5D Physics

admin — Wed, 02 Aug 2023 16:21:47 +0000

For a new project, I wanted to go with a 2.5d solution. Unfortunately, for optimization, Unity does not allow the rotation of terrains and mesh-based terrains wouldn't be ideal. In order to allow for exciting background scenery, while keeping the illusion of a 2D game, movement along a spline would be important.

Für ein neues Projekt wollte ich eine 2,5D-Lösung verwenden. Leider erlaubt Unity aus Optimierungsgründen keine Drehung von Terrains, und meshbasierte Terrains wären nicht ideal. Um spannende Hintergrundlandschaften zu ermöglichen und gleichzeitig die Illusion eines 2D-Spiels zu bewahren, wäre eine Bewegung entlang einer Spline wichtig.

Per un nuovo progetto, volevo optare per una soluzione 2.5D. Purtroppo, per motivi di ottimizzazione, Unity non consente la rotazione dei terreni e i terreni basati su mesh non sarebbero l'ideale. Per ottenere uno scenario di sfondo emozionante, pur mantenendo l'illusione di un gioco 2D, sarebbe importante il movimento lungo una spline.

For the splines, I started with BansheeGz/BGCurve.

Für die Splines habe ich mit BansheeGz/BGCurve begonnen.

Per le spline, ho iniziato con BansheeGz/BGCurve.

The core function is to have the object always looking forward, by calculating the tangent of the closest point.

Die Kernfunktion besteht darin, das Objekt immer nach vorne schauen zu lassen, indem die Tangente des nächstgelegenen Punktes berechnet wird.

La funzione principale è quella di mantenere l'oggetto sempre rivolto in avanti, calcolando la tangente del punto più vicino.

The Y axis needed to be freed to allow for gravity, and to smooth out the physics I also projected the velocity along the spline.

Die Y-Achse musste freigegeben werden, um die Schwerkraft zu berücksichtigen, und um die Physik zu glätten, habe ich auch die Geschwindigkeit entlang der Spline projiziert.

L'asse Y doveva essere liberato per consentire l'azione della gravità e, per uniformare la fisica, ho anche proiettato la velocità lungo la spline.

Lattice Mesh Deformer

admin — Sat, 03 Dec 2022 12:06:32 +0000

To get a toon look for architecture, I needed a lattice deformer. There is an open source solution which nearly did the trick, but the bounds function was broken.

Um einen Cartoon-Look für die Architektur zu erzielen, benötigte ich einen Gitter-Deformer. Es gibt eine Open-Source-Lösung, die fast das gewünschte Ergebnis lieferte, aber die Bounds-Funktion war defekt.

Per ottenere un effetto cartoonesco nell'architettura, avevo bisogno di un deformatore a reticolo. Esiste una soluzione open source che quasi funzionava, ma la funzione di delimitazione era difettosa.

The bounds functions had to be rewritten.

Die Bounds-Funktionen mussten neu geschrieben werden.

Le funzioni dei limiti dovevano essere riscritte.

Scale and global positioning needed to be respected.

Maßstab und globale Positionierung mussten beachtet werden.

Era necessario rispettare le dimensioni e il posizionamento globale.

In order to keep the effect within the bounds, the source vertices needed to be clamped.

Um den Effekt innerhalb der Grenzen zu halten, mussten die Quell-Scheitelpunkte begrenzt werden.

Per mantenere l'effetto entro i limiti, è stato necessario bloccare i vertici sorgente.

There was also some unecessary math happening in the runtime code. I was able to get more FPS by correcting it.

Es gab auch einige unnötige Berechnungen im Laufzeitcode. Durch deren Korrektur konnte ich mehr FPS erzielen.

C'erano anche alcuni calcoli matematici superflui nel codice di runtime. Sono riuscito a ottenere un numero maggiore di FPS correggendoli.
