Hey, I've managed to fix most issues. The approach I took was to copy most of the PlayerRenderer code and adjust it to my needs in the RenderPlayerEvent.Pre. Now, the issue I have is that I can't get the armor to render. I see that in the PlayerRenderer constructor the armor layers are set up from something called EntityRendererProvider.Context, but I can't seem to find where to get this context from. I did try to extend the PlayerRenderer class into my own with my needed modifications, but I can't seem to register it as a replacement to the vanilla PlayerRenderer. Altough I'm thinking this might not be the best approach because it might make other mods incompatible. This is the relevant code of the RenderEvent if needed: @SubscribeEvent public static void onPlayerRender(RenderPlayerEvent.Pre event) { // Note: conditions are not yet setup, I'll do it once I get the render right event.setCanceled(true); final PoseStack poseStack = event.getPoseStack(); final MultiBufferSource buffer = event.getMultiBufferSource(); final PlayerRenderer renderer = event.getRenderer(); final PlayerModel<AbstractClientPlayer> playerModel = renderer.getModel(); final Entity entity = event.getEntity(); final float ticks = event.getPartialTick(); final LivingEntity livingEntity = event.getEntityLiving(); final AbstractClientPlayer abstractPlayer = (AbstractClientPlayer) event.getPlayer(); event.getPoseStack().pushPose(); // Set the model attack time playerModel.attackTime = event.getEntityLiving().attackAnim; boolean shouldSit = entity.isPassenger() && (entity.getVehicle() != null && entity.getVehicle().shouldRiderSit()); playerModel.riding = shouldSit; playerModel.young = false; float f = Mth.rotLerp(ticks, livingEntity.yBodyRotO, livingEntity.yBodyRot); float f1 = Mth.rotLerp(ticks, livingEntity.yHeadRotO, livingEntity.yHeadRot); float f2 = f1 - f; if (shouldSit && entity.getVehicle() instanceof LivingEntity) { LivingEntity livingentity = (LivingEntity)entity.getVehicle(); f = Mth.rotLerp(ticks, livingentity.yBodyRotO, livingentity.yBodyRot); f2 = f1 - f; float f3 = Mth.wrapDegrees(f2); if (f3 < -85.0F) { f3 = -85.0F; } if (f3 >= 85.0F) { f3 = 85.0F; } f = f1 - f3; if (f3 * f3 > 2500.0F) { f += f3 * 0.2F; } f2 = f1 - f; } float f6 = Mth.lerp(ticks, livingEntity.xRotO, livingEntity.getXRot()); if (LivingEntityRenderer.isEntityUpsideDown(livingEntity)) { f6 *= -1.0F; f2 *= -1.0F; } if (livingEntity.getPose() == Pose.SLEEPING) { Direction direction = livingEntity.getBedOrientation(); if (direction != null) { float f4 = livingEntity.getEyeHeight(Pose.STANDING) - 0.1F; poseStack.translate((double)((float)(-direction.getStepX()) * f4), 0.0D, (double)((float)(-direction.getStepZ()) * f4)); } } float f7 = livingEntity.tickCount + ticks; setupRotations(livingEntity, poseStack, f7, f, ticks); poseStack.scale(-1.0F, -1.0F, 1.0F); poseStack.translate(0.0D, (double)-1.501F, 0.0D); float f8 = 0.0F; float f5 = 0.0F; if (!shouldSit && livingEntity.isAlive()) { f8 = Mth.lerp(ticks, livingEntity.animationSpeedOld, livingEntity.animationSpeed); f5 = livingEntity.animationPosition - livingEntity.animationSpeed * (1.0F - ticks); if (livingEntity.isBaby()) { f5 *= 3.0F; } if (f8 > 1.0F) { f8 = 1.0F; } } playerModel.prepareMobModel((AbstractClientPlayer) livingEntity, f5, f8, ticks); playerModel.setupAnim((AbstractClientPlayer) livingEntity, f5, f8, f7, f2, f6); // This is the part responsible for making the player translucent, specifically the RenderType#itemEntityTranslucentCull event.getRenderer().getModel().renderToBuffer( event.getPoseStack(), event.getMultiBufferSource() .getBuffer( RenderType.itemEntityTranslucentCull( event.getRenderer().getTextureLocation((AbstractClientPlayer) event.getPlayer()))), event.getPackedLight(), 0, 1.0f, 1.0f, 1.0f, 0.8f); event.getPoseStack().popPose(); } // Direct copy of PlayerRenderer#setupRotations private static void setupRotations(LivingEntity entityLiving, PoseStack pMatrixStack, float pAgeInTicks, float pRotationYaw, float pPartialTicks) { if (entityLiving.isFullyFrozen()) { pRotationYaw += (float)(Math.cos((double)entityLiving.tickCount * 3.25D) * Math.PI * (double)0.4F); } Pose pose = entityLiving.getPose(); if (pose != Pose.SLEEPING) { pMatrixStack.mulPose(Vector3f.YP.rotationDegrees(180.0F - pRotationYaw)); } if (entityLiving.deathTime > 0) { float f = ((float)entityLiving.deathTime + pPartialTicks - 1.0F) / 20.0F * 1.6F; f = Mth.sqrt(f); if (f > 1.0F) { f = 1.0F; } pMatrixStack.mulPose(Vector3f.ZP.rotationDegrees(f * 90.0F)); } else if (entityLiving.isAutoSpinAttack()) { pMatrixStack.mulPose(Vector3f.XP.rotationDegrees(-90.0F - entityLiving.getXRot())); pMatrixStack.mulPose(Vector3f.YP.rotationDegrees(((float)entityLiving.tickCount + pPartialTicks) * -75.0F)); } else if (pose == Pose.SLEEPING) { Direction direction = entityLiving.getBedOrientation(); float f1 = direction != null ? sleepDirectionToRotation(direction) : pRotationYaw; pMatrixStack.mulPose(Vector3f.YP.rotationDegrees(f1)); pMatrixStack.mulPose(Vector3f.ZP.rotationDegrees(90.0F)); pMatrixStack.mulPose(Vector3f.YP.rotationDegrees(270.0F)); } else if (LivingEntityRenderer.isEntityUpsideDown(entityLiving)) { pMatrixStack.translate(0.0D, (double)(entityLiving.getBbHeight() + 0.1F), 0.0D); pMatrixStack.mulPose(Vector3f.ZP.rotationDegrees(180.0F)); } } // Direct copy of PlayerRenderer#sleepDirectionToRotation private static float sleepDirectionToRotation(Direction pFacing) { switch(pFacing) { case SOUTH: return 90.0F; case WEST: return 0.0F; case NORTH: return 270.0F; case EAST: return 180.0F; default: return 0.0F; } } }

Thank you, I got really far by looking at how LivingEntityRenderer#render works, though I'm not sure if the way I did it is the most optimal one. There is one problem that I'm having a hard time figuring out, the render just does a lot of popping. I attached a video below (ignore the rotation, I already fixed it): On another note, how would I go about rendering this event conditionally? Should I use packets or is there another way?

Yes, I'm using parchment mappings. This is what I see when rendering the body with less transparency: As you can see, the rotation and placement is wrong. And this is the code snippet from the RenderPlayerEvent.Pre event: @SubscribeEvent public static void onRenderPlayerPre(RenderPlayerEvent.Pre event) { // Commeted this out to see if the body renders in the correct position but didn't work. //event.setCanceled(true); PlayerRenderer renderer = event.getRenderer(); PlayerModel<AbstractClientPlayer> playerModel = renderer.getModel(); AbstractClientPlayer abstractPlayer = (AbstractClientPlayer) event.getPlayer(); // This is the part where I think I'm getting the wrong arguments to send to the render function. Or maybe I don't have to use this function at all... playerModel.body.render(event.getPoseStack(), event.getMultiBufferSource().getBuffer(RenderType.entityTranslucentCull(renderer.getTextureLocation((AbstractClientPlayer) event.getPlayer()))), event.getPackedLight(), 1, 1.0f, 1.0f, 1.0f, 0.5f); }

I've managed to get the torso rendering with transparency but it appears stuck to the ground. Is there a way to render the whole model with transparency or do I have to do it part by part? How can I put the new torso in place of the old one? I'm guessing I have to cancel the event and replace the render with my own but I'm having a hard time figuring out where to get some arguments from.

Do you mind writing an small code example? ModelPart#render seems to need a lot of arguments and I don't really know where to get them from. Appreciate it!

Could anyone point me in the right direction in how might I achieve this? Been looking through the forum and the internet and couldn't find and updated answer. Most answers I found talked about GlStateManager which seems to no longer be used.
