Unit 69
For this unit I have to create one asset that is going to be a main feature of the game I am building for unit 18, it has to be below 8,000 trails, fully textured and have a high to low poly bake as well.
For my gramophone model i wanted to create a levels of detail on the model for when it is ready to go into unreal engine. Level of detail is when the model decreases the tris of the model when the player moves away from the model, this helps performance on all platforms as there is less geometry for the graphics card and processor to process and render. The level of details has to a gradual decrease so there is no noticeable change between the normal model and the level of detail models I did some research on how to apply level of details to models in unreal engine and found this video on it, even thou they used 3D max as the 3d application it can be easy translated to Maya. I started off by duplicating my model in Maya and adding it to a new layer, i select edges that are not needed as much as the core edges in the model that would change the shape of the model In the photos above i removed the edges i placed in the model to keep the edges sharp for the high poly bake this reduced the the tris down from 7102 to 6094. i repeated the process by duplicating the level of detail model and placing it into a new layer and removed more edges from the model with out changing the shape to much. i lowered the second level of detail down to 5558 tris which is over 600 less between the level 1 and 2 this till be the furthest way level of detail and the level one will the middle distance. In total i lowered the tris by 1544 which would improve the performance of the game when far away with the model in view. After i created the models i exported them as FBX files and opened the level with my model in and open the settings of the model and went down to the LOD settings and imported the two level of detail models Each LOD has it own settings and displays how many triangles and vertices each model has and at the distance it changes to that model. the LOD1 is set to come when the normal model is 0.333 of the size of the default scale and the level 2 comes on when its 0.167 of the size of the default scale. here is a video of me scrolling out and into the model to see if the model changes to different level of details and to see if there is any major changes
